As I mentioned here, I’m fine with Hatch providing this unified UX since it really is almost there already. The only thing that is out of my control is the lock file standardization which Brett discusses here.
As far as resources go, this is the only side project that I am working on nowadays and we use it at work so time allocation shouldn’t be an issue. Also we have some great contributors now, for example they just completely added type hinting to Hatchling. Another boon here as designed is the concept of plug-ins so maintenance is distributed.
