AFAICS RFC 3112 was never implemented in OpenLDAP. Thus I'd consider
this to be rather irrelevant here.

Incorrect, it's clearly implemented in slapd.  Whether it's enabled is a
different question, as it's IFDEF'd behind SLAPD_AUTHPASSWD. ;)

In any case, I've been advocating for several years now to get rid of
SSHA  as the default hashing mechanism and replace it with something
that may  actually have some security value.

Is a "well-salted" SHA-1 really worse than a "poorely-salted" SHA-256?
Isn't it all aboput the number of bits that have to be checked
(brute-force)?

As Howard already noted, what we're looking for is something like Argon2, not further SSHA derivatives.
