This is a common misconception.

In fact, for a large number of packages in main, especially those
installed by default in the Desktop task, we maintain them ourselves
based on the original Debian packaging but updated to the current
upstream released version.

Remember, a new version brings just as many, if not more, bug fixes than
it does new problems.

glibc has an almost zero number of ABI breakages (I'm not aware of one
in its recent history), updating this means that we support the latest
software from vendors whilst *still* supporting software compiled for
warty.  Our packaging system is more strict about this, of course; but
that's not a problem with glibc.
