I have to admit that contrary to OpenMP, that I followed very closely,
I only superficially followed flang development. Thus, I stand
corrected by Mehdi and Eric here.

I said "we may end up" -- or we may not. :-) No particular reason
apart of history of software engineering. As you said, clear
expectations from the very start are a key ingredient to avoid this
happening.

IMHO, it's infinitely better to start project development in a wide
and mature open source community ASAP -- at expense of some potential
refactoring work -- rather than delay until code is "good enough".
This says a man who spent most of his life working on proprietary
projects and used to argue with Chandler that "proprietary development
model is less expensive and leads to higher quality" (now I know
better). Just one man's opinion. It's fine to disagree.

Yours,
Andrey
