Since we run a stock standard bugzilla we found out about the removal the hard way. From an admin point of view I'd prefer not to modify bugzilla as changes get lost or need to be reimplemented each time bz is upgraded.
However, after watching how ppl in freedesktop.org work, it's clear we do need something; I think implementing NEEDINFO as a keyworks is the best option for now and hence I've now added:
NEEDINFO
as a keyword. To get a list of all the bugs without the keyword sadly an advanced search (https://bugs.freedesktop.org/query.cgi?format=advanced) is needed. If you don't want to figure out the advanced search simply add:
&keywords_type=nowords&keywords=NEEDINFO
to any search url and you'll get the relevant bugs removed - you can then save that as a custom search.
