Heartily disagree. ;-) For those of us who have to maintain it, they are 
interesting and of importance. But I agree the questions you raise below 
are more important.

Heartily agree with the whole list (snipped).

If we are making custom fields product-specific instead of global (which 
I believe is the plan), then we shouldn't add them to the bugs table.

Giving each field a separate table means that every Bugzilla which uses 
custom fields will have a different schema. This could really come back 
to bite us.
