TL ConTeXt in minimal setup

Yeah, I've had this issue too. Running 

   $ mtxrun --generate
   $ context --make

should fix it. ("context --make" is probably not needed, but ConTeXt
will need to run it anyways, so it doesn't hurt)

Does installing the "context-texlive" package fix anything? I'd guess
no, but that might explain why a full install works differently from a
minimal install.

This is probably related to either the LMTX upgrade or tlmgr no longer
ever running "mtxrun --generate". Or maybe a combination of them both.
