Deletion of Tacit extension

Comment: Specialized terminology often has room for expansion to an article beyond a dictionary definition and etymology. Keep for a while, try to get someone to improve it, and if it can't be done then delete per #DICT. About 1,000 Ghits for '''"Tacit extension" -wikipedia -wiki''', so I'd give a very small benefit of the doubt
Stance: keep
