I wonder for keywords that would be awkward to "force" into the
description if we could have an "extra keywords" section?  Then we can
skip tagging, but in case a package's description didn't comfortably fit
that word, you can still find it by it.  Then it's not separate tagging,
just extra words to find a package by that the description didn't say.

WDYT?
