Supported Features Matrix

[No9]

Following the Collaboration Call - 2022-08-09
Opening this issue to capture discussion on features that we should remove, disable, focus on
I've captured
Backwards Compat - #404 (comment)
JS API - #388
Release a 3.3.0 as a final 3.x build with llvm14 features but no official support?

But there maybe others we can discuss on the next collab call.

Looks like we are struggling to support Mac ARM architecture
Also need to document supported architectures following on from #401 (comment) and validate for power and s390.
