IMHO Prism is not even Delphi. Just recycling of the brand.

I'd rather see the time spent on features that really matter (like generics,
SEH/COM support, unicode).

If a feature is not supported by delphi, the usage is usually very low
(since most people don't even know about it, and some are limited by
compatibility requirements), except in the rare cases that it is really used
a lot (like in the past the pointer overindexing and the exit() features.
But they are no longer extensions, since D2009 Delphi has them too)
