The exact use of the release keywords is not entirely clear to me. Please
update the wiki page to make it more explicit how to use them, what to do
with the bug state for something fixed on trunk but needing backports, etc.
The other flags and keywords seem mostly relevant to the procedures of a
triage team. IMHO the most important thing is to actually get such a team
assembled and active. Then they can hone the bugzilla process details.
