[exim] Feature Request - Exim needs more MySQL Support

I may be missing something by MySQL support in Exim seems to be limited
to lookups rather than just the ability to randomly run any MySQL
command I want. It also seems to lack MySQL support in the filter language.

I'm in the process of trying to do some really kool stuff and fighting
the Exim syntax to get anything done. However - I might be missing
something as I often do.
