Sees reasonable, although I should say that I don't use the "upgrade"
machinery in GS at all.

This is a bug: QI should probably be displaying *all* extension
profiles registered for the site root interface, rather than trying to
bless one per product.

Proposed changes to QI aren't exactly in scope on this list.

Yes, I use multiple profiles.

No. The name 'default' should *definitely* not be majyk.
