I vaguely remember reading that the motif was similar as for the
complex data types. There are platforms with specialized compilers
that really don't need VLA (embedded stuff comes into mind). They
shouldn't lag behind in addopting the core features of modern C. The
same strategy has been followed for other new features such as
threads, for example.

Up to now, there was the main difference in hosted and standalone
environments. This classification was perhaps to coarse. With C11, C
becomes a toolbox with optional modules that is build arround some
sort of core language.

It is really unfortunate, that we don't have the rationale document
for C11, yet.
