I don’t think they should.  There are many more environment variables
needed by a usual TeX Live installation, but they are usually configured
in “texmf.cnf” and with special syntax e.g. to permit recursive
traversal (ending on “//”).  These three variables are just the bare
minimum I needed to run “latex” or “luatex” on the packages up to this
point.

If we really do need more in the future it might be better to create a
custom “texmf.cnf” and set the TEXMFCNF variable to use it.
