imho that is *not* sufficient to keep from Doing The Right Thing. And
DTRT usually means designing correctly for the future. I would support a
design that is cleanest for the next release, and put backward
compatibility a (no so) distant second.

I've been wanting to think about the "package" or "module" idea (which
others have brought up recently). If this kind of hook gets us more
options to support that (e.g. running a routine when the module is first
loaded to install new options into "SET key=val") then even better. Lack
of hooks of this nature lead us to push datatypes down into the core
when if we had full-up module support we could make more things
loadable.
