Spot on.  If this was a valid argument, we would have 'allowed'
underscores all along since our favorite friend M$ has for as long as I
recall.  If vendor foo jumps off a cliff, should we too?

As I see it there are standards published.  Some vendors choose to ignore
standards making life hard for everyone.  Follow standards.  Believe it or
not, they come to exist for a reason.  OTOH, if you don't like the
standard, work to effect change.  Specifically, change or update the
standard and promote conformance.
