What I had in mind back when I raised this is that the extension
prefix is not a variable, it's a naming convention so if we used
to provide a db table for an extension, $wgDBprefix would still be
applied to give
Within the extension code, the extension developer would hardcode
et_extensiontable, and the MW database methods would prepend
$wgDBprefix as needed.
The naming convention just assures that extensions will never add
tables with names that clash with table names added by the MW core
devs. To prevent clashes between extensions, we'd add a registry
page on mediawiki.org.

So, I was not proposing a variable. See above. But no need to
apologize. If it wasn't clear, it was probably that the proposal was
