Making the core smaller isn't easy for users - they suddenly don't have
to are about a single version number anymore but check which version of
which extension makes a feature available, and how that relates to the
core version as core provides infrastructure and extension feature might
use conditionally. It's a question of balance and I think right now we
are in a quite good area.

Yes and no. In practice most security issues (not that there are
many ..) are in core areas not an extension, so the core part has to be
updated. Splitting things up again gives more components to handle and
makes update processes more complicated. And in practical terms:
Distributions split up all non-forced extensions ... but they, contrary
to us, have a package dependency system which mostly works and on which
they can build upon.
