[Semi-OT] Trackers in Bugzilla?

[Stewart Gordon]

In Bugzilla installations I have used before, such as Mozilla's own, a 
fairly common phenomenon is tracker bugs, aka meta bugs.

These are issues filed not to report specific bugs or request specific 
features, but to group together related bugs.  For some examples of what 
I'm on about, see

This is useful for issues with some aspect of a product smaller than a 
component.  Or for creating groups of some nature for which a component 
or keyword isn't exactly appropriate.  Moreover, anybody can create 
trackers, whereas only an administrator can modify the list of keywords 
or components.

I had just been thinking about filing a tracker or two in our Bugzilla, 
but I thought I should ask here first.  Does anybody here have any 
problems with this?

Stewart.
