Not that I can see. It seems that Embarcadero used it mostly for own
purposes, not the users, and their support scenarios.

I see it as a cost/benefit tradeoff. It is not the namespace added feature
that I worry about, but the fact that you force all existing users to find
out what is going on and set default namespaces in their projects.

True. But it is now the time to force this XE2+ breaking change, while
you are so opposed of doing the same for the D2009 string change?

And at least that is a major deal, the namespace stuff is rarely benefiting
anybody, but forcing updates on all.

So let's not introduce them then. Or at least wait with breaking changes
till the platform is there and older versions are mostly dead.
