This sounds like a reasonable goal.  Intuitively, you want stronger 
randomness for hashing a password than for generating UUIDs.  Then 
again, it's not clear how much stronger exactly.  RFC 9562 does call for 
"cryptographically secure" random numbers.  Do we want multiple levels 
of "strong" or "secure"?  This needs a lot more analysis.
