It isn't to me either - but I'm sure people here have included those files from time to time with their projects. I can't see any reason why there should be a problem with doing that.
I don't think it's a problem I've encountered on any of my machines - probably because they get installed anyway by various applications that I have. For example, as of U7.4 DBPro places two of those files into the Compiler folder.
Just go ahead and include them - and if Microsoft complains blame me.
