I think that would be ok, except I can see somebody relying on it.

It's broken, it's stupid, but we've done that ETXTBUSY for a _loong_ time.

But you are right that we have removed parts of it over time (no more
MAP_DENYWRITE, no more uselib()) so that what we have today is a
fairly weak form of what we used to do.

And nobody really complained when we weakened it, so maybe removing it
entirely might be acceptable.
