There probably isn't anyone using them, yet, which seems to me to be
a good argument to fix any obvious deficiencies in the API *now*
before there actually is anyone who'll be affected.  In particular,
I suggest that 9.0 would be a good time to add an "int flags" parameter
to the add_xxx_reloption functions.  The first flag could be
default_only and we'd have room to add more later without another API
break.
