Again, software should provide capability, not set policy.
If different users want different policies, it sounds like the code
needs a switch.  Wither that's run-time or compile-time is open to debate [*].
But as long as it's cleanly (unobtrusively) written, nobody should object
to having options available.

[*] and of course in most cases that debate is won by the person who first
submits a working patch.
