Well, SAP is also one of them.  I can sort of understand that in cases
where the Software Product is tightly related to e.g. boot concept or
filesystem hierarchy.
IDL is not such a product, so I cannot understand their position.

The only important thing is libraries, indeed.

And there, opposite to the claims of RSI before, the problem often
even reverses, e.g. you have to upgrade your system software because
you want to upgrade some software package that is linked against newer
versions of a library.

The other way around (upgrade of the system but keep old version of
software) is *never* critical for an open source system, as
you always will have the option to get/keep the old version of the
libraries, too (I still run an IDL 4.01 (libc4) on a SuSE 6.4
(glibc2.1) system.

Indeed, that's what it is in most cases:  Excuses, not reasons.
