Ad 1) If C99 (or C11) was supported, you could perhaps use C99/11's features to refactor parts of the legacy code into more elegant code than possible with C89 (and yes, there are sometimes good reasons not to use C++).
Ad 2) If there is support for features there will be people using them.
C90 isn't going away, and it's not Microsoft's fault. Many C compilers still support 1st edition K&R style for a reason — old C code is going to stick around, and it's probably not going to change much, let alone in any way that needs C99 features.
