I fail to see how 'Traditional Latin Mass' fails to convey something that 'extraordinary form' does. TLM refers exactly to what you mean. Everyone knows it. Up until Summorum, that's what it was known as and no one had a problem.
'EF' is a compromised phrase, a lie, and just wrong. If the TLM was never abrogated, it takes precedence/priority over the NO due to age and constancy of offering.
To say anything like EF is to lose the war of words, and words are very important.
