This is honestly the first thing I look for with anything new claiming "CAD".

Roughly every other week there is a new "The (programmable) CAD that fixes everything!" post on the front page, just for me to open them up excitedly and noticing that they use a mesh kernel and will thus never be able to provide fillets and chamfers painlessly (for the user). All while they are absolutely essential for a lot of designs, especially in 3D-printing, a well-placed fillet/chamfer can make the difference between an object that breaks upon looking at it funny and one that can bear significant load.

Yeah, it's a tough row to hoe --- I've been handling it quite differently in my own project, taking "Design for Manufacturing" to the ultimate conclusion and requiring that the part be designed by actually applying tooling:

Needs a full-on re-write to make the G-code export (and import) work well, but lately I've been focused on exporting to DXFs w/ colour/layer tagging which was just added as an import feature in the CAD tool my side-gig employer does.

G2 fillets are the next frontier. Even Fusion doesn't seem to handle them well. I mean they can be created without much drama, but geometry derived from them is very likely to fail with no real reason.
