There were factions that wanted a library wrapper that wraps a VLA and
remembers the size. We had reports that
that wrapper causes implementation difficulties. And then we ended up
not having consensus to explore such wrappers
further, and we didn't have consensus for standardizing just a plain
VLA without the wrapper.

And then there's other things, like sizeof always being a compile-time
operation in C++, and many of us wanting to keep
it that way. That probably wasn't a major part of it, but it's
certainly something where C and C++ are bound to clash.
