But client can control that behaviour - it just needs to specify
suites it wants and drop the rest.

So only question is that does any client have better (non-tuned?)
defaults than we can set from server.

Considering the whole HTTPS world has answered 'no' to that question
and nowadays server-controlled behaviour is preferred, I think it's
safe to change the behaviour in Postgres too.
