- We've got significant missing features in order to use most of these effectively (i.e. custom builders, region-based builders).
- We presently also lack a mechanism for actually registering these dialects but they can be use with contexts that allow unregistered dialects for further prototyping.
We don't need to test completeness: i.e. no need to test every feature from ODS, just basic plumbing here (import and create / round-trip one or two ops), that's why I mentioned "smoke test".
I guess it'll be more useful with the registration aspect sorted out.
