Greg clarified on the core extensions page text:
"These core extensions supply useful features in areas such as
database diagnostics and performance monitoring."
None of those others perform such a role. Instead they add additional
functionality intended to be utilised as part of general data usage,
adding new types, operators, query functions etc. Maybe the term
"core" is inappropriate. Instead we might wish to refer to them as
"utility extensions" or something like that, although that may be just
as vague.

Backwards compatibility. No-one will use it except if they're coming
from an older version.
