I was simply stating that ideas and practice are two different things.

For the idea of moving ports to ports only OpenSSL there were some big 
problems regarding ports crossing the boundary between base and ports 
(can't link to two different SSL implementations at the same time) and 
the need of a lot of testing and work. There simply was not enough time 
in the 14.0 rleease timeframe.

It can still be done though, nothing is lost.

This can change, anyway. Also, the thread you linked shows the proposal 
was formally accepted, let's see how things evolve.

Yes you do in the sense that one need to do one thing or some other 
thing between two or more options.

Regarding "rustification" the options are, we upgrade ports of software 
being moved to rust or gaining rust dependency (which is what we are 
doing and I think is the correct thing for a ports collection that has 
no role being judgemental about the ported software).

Or we do something else. For example we abstain from upgrading software 
that moves to rust or gaining rust dependencies (keeping the last non 
"rustified" version). [1]

Or we do something else that I have not thought about. (I'm not trying 
to trap the discussion in a false dicotomy, but I see no other possible 
courses of action)

In other words, what are the options we have?


[1] I also think this is wrong for the ports tree because it's giving 
value judgements about ported software which is not the ports tree role 
and would be a bad service to all users except the ones which strictly 
agree with such value judgement

Actually the change you mentioned is to both base and ports, I stil 
lthink it would be a good idea, but requires time and a lot of work/testing.

Also that proposal can be applied and has no real relation to rust. It 
is a good proposal in itself.

It would only marginally address the rust issue.

BTW (I have not thoroughly checked or tested this) we do have a 
DEFAULT_VERSIONS= pycryptography=legacy flag, and latest head (and 14.0 
I guess) should have compatibility shims to make it work. Not sure it 
does actually work though, just an observation.
