svglite vs systemfonts: at a glance
What is svglite?
svglite caught up to the modern graphics engine, and paid for it in editable text.
svglite is the lightweight SVG device that replaced the cairo path for R vector output, and its value proposition has always been clean, hand-editable SVG. The 2.x line has spent its releases closing the gap with R's graphics engine: clipping, masking, patterns and gradients in 2.1.0, then groups, affine transforms, colour blending, path stroking and glyph support in 2.2.0. The two releases since are a Fedora compilation fix and a sanitizer error.
What is systemfonts?
The R font layer stopped matching fonts and started acquiring them.
systemfonts is the font matching and shaping engine underneath ragg, svglite and textshaping, and its recent releases have pushed it well past its original job. It can now register uninstalled font files, pull fonts from Google Fonts and Bunny Fonts, emit stylesheet imports for HTML and SVG embedding, and hand glyph outlines and bitmaps to other C-level consumers. The last two releases are pure upkeep: a FreeType compilation fix, a sanitizer issue, and a workaround for a broken macOS system font.

svglite caught up to the modern graphics engine, and paid for it in editable text.
◆ Current state
svglite is the lightweight SVG device that replaced the cairo path for R vector output, and its value proposition has always been clean, hand-editable SVG. The 2.x line has spent its releases closing the gap with R's graphics engine: clipping, masking, patterns and gradients in 2.1.0, then groups, affine transforms, colour blending, path stroking and glyph support in 2.2.0. The two releases since are a Fedora compilation fix and a sanitizer error.
◆ Where it's heading
The package is converging on feature parity with what ggplot2 and the graphics engine can now emit, and the seams are showing. Glyph support renders text as paths or rasters, which the release notes concede is not editable in post-production — the exact property svglite exists to provide. Porter-Duff composition was dropped outright because SVG support for it is poor. The direction is fidelity first, editability second where the two conflict.
◆ Prediction
Expect the next feature release to pick up systemfonts' variable font API, and expect the editable-text regression from glyph rendering to be revisited as an opt-in rather than left as the only path.

The R font layer stopped matching fonts and started acquiring them.
◆ Current state
systemfonts is the font matching and shaping engine underneath ragg, svglite and textshaping, and its recent releases have pushed it well past its original job. It can now register uninstalled font files, pull fonts from Google Fonts and Bunny Fonts, emit stylesheet imports for HTML and SVG embedding, and hand glyph outlines and bitmaps to other C-level consumers. The last two releases are pure upkeep: a FreeType compilation fix, a sanitizer issue, and a workaround for a broken macOS system font.
◆ Where it's heading
The arc is from passive lookup to active font provisioning. Variable font support in 1.3.0 is the clearest marker — it is explicitly gated on downstream packages upgrading to use it, which means systemfonts is now setting the pace for the rest of the R graphics stack rather than following it. Reference counting on cached faces points the same direction: the package is being hardened as a shared resource other packages hold handles into, not a leaf utility.
◆ Prediction
Expect the deprecation of the bold argument in favour of weight to complete, and expect the variable-font API to show up in ragg and svglite before it shows up in user-facing packages.
