Well, it's never the same 20%, which is precisely why we have plugins and extensions even outside of the Linux GUI bubble. This include IDEs, browsers, office suites, media production software (e.g. VST), and of course engineering software. For a complex software product, it is never possible to include batteries for everyone.
FreeCAD might not come with enough battery to power a full workflow, but I have also seen entire engineering firm not able to work without a particular AutoCAD plugin.
