I think there is still at least a potential for problems around the use of FLAG_IS_CMDLINE in
the constraint functions, but I don’t see an actual problem at this time.  Another issue besides
those I’ve mentioned before is that if the constraint is only active when FLAG_IS_CMDLINE
and no command line option was given, but the option is manageable and later set through
that interface, I think the constraint won’t check the new value being provided.  However,
none of the options with new constraint functions using FLAG_IS_CMDLINE are manageable,
so I think there’s no immediate problem on that score.  But there should be an RFE to
follow up in this area.

So looks good to me.
