FontGoggles for .glyphspackage?

The excellent FontGoggles app is recommended in forum posts and touted on the Tools page.
One of its features I only realized recently is that when set up with a .ufo file, the app can watch for changes to the file on disk and update its display to show them.
Is there any motion to get this kind of support in the app for .glyphspackage files (which I take it are structurally similar to .ufo)?

This feature relies on fontMake. It could work with glyphsLib. But it doesn’t support .glyphs 3 files or .glyphsPackages, yet.
