Various problems with ENUM have been presented,
and it appears that its use cases may be better accommodate
in db schemas for MediaWiki by other means.
I'm looking for the following:
* Success stories with ENUM (cases where it's not only good but better than
alternatives).
* Horror stories or scenarios we not yet covered.
These would influence the direction, our options are currently:
* Keep allowing it and encourage it for cases where its good.
* Start discouraging it in general, but document cases for which it makes
sense.
* Disallow by default (in policy). New usage would require approval through
some other method (e.g. DBA feedback or some such).
