It's already implemented. Built-in fonts have lower font version than native ones, so if native font exists it gets used instead of a built-in one.
Problem in the bug 34446 is completely unrelated. Moreover, Tahoma has never been a part of the original Microsoft web fonts pack, so in order to use it one needs a Windows license.
I have a Windows license and I own this font legally. You sound like people who have this font installed should experience a bad font rendering only because others don't have a Microsoft version.
