I'd like to throw my low-token-budget hat in the ring:

iteration-focus is slightly there, i.e. fast hotpatching. But been focused on beating LLVM's compiled runtime performance as of late.

"Viable" in scare quotes, as it should be. Note that the third one you listed is forked from the second one with licensing credit stripped. None of them are actually used by anybody programming anything real. Calling this commoditization is ridiculous.
