Yeah, I don't see why that should affect anything. SCRAM with a poor
random function is probably still better than MD5.
As I recall, the reason for not defaulting to SCRAM right away had
nothing to do with that; it was worry about how many clients would
get locked out for lack of SCRAM support. But the list at
https://wiki.postgresql.org/wiki/List_of_drivers
looks pretty positive, and another year would probably be enough
to give the stragglers time to catch up ... especially if they know
this is coming.
