I agree that it is nowhere in the manual, but none the less the title of the 
pdf refers to it as the Gen2_UMC_Manual. Weather it is legacy or not is a mute 
point, Tesla identifies it as Gen2 UMC.

Tesla refers to it everywhere publicly as a "mobile connector".  Minor change, 
but that's what they did.  Note that the term "UMC" or "Universal Mobile 
Connector" is seen nowhere in the manual text at all, nor is it anywhere in 
their documentation.  The URL doesn't matter, it could just be legacy.

You'll note the Tesla link "gen 2 umc".
https://www.tesla.com/sites/default/files/pdfs/charging_docs/gen_2_umc/Gen2_UMC_Manual_en_US.pdf
So Tesla does keep  the name Gen 2 UMC
