This question has been superseded by Can we please standardize the Microsoft tags?.
This was a huge mistake. There's no reason to create those huge tags, when the small ones were understandable by everyone. The non-microsoft tags have worked fine on SO for the last few years without confusion for excel and powerpoint. Access is ms-access and word is split between msword and word (on SO). It makes no sense to just make them bigger and more cumbersome, and it's completely unnecessary.
