Huuu? That would be a bug!

No, if fmtutil-local.cnf is in the right directory, the one
you mentioned below
	$(kpsewhich --var-value=TEXMFLOCAL)/web2c/fmtutil-local.cnf
a call to
	tlmgr generate fmtutil
will include it automatically!

Please retry, if it is not working as advertised let me know.

Maybe it is simply a documentation issue, and I didn't explain
it clearly enough in the help page.

No, you *can* disable a format by putting a line
into it, the pdflatex format as defined in the tlpdb will *NOT*
be included in the generated fmtutil.cnf file.

Why? There is currently no way to permanently disable a format
definition idirectly in the tlpdb, only in the fmutil-local.cnf

So if you want to replace pdflatex format with one of your own definitions,
then inlcude:
	pdflatex myengine .....
and it will work.

The only explanation I see at the moment is either a misunderstanding
of the documentation on your side, or a misunderstanding of your
request on my side, or a bug in tlmgr.

Please let me know which you think is most appropriate.

that it renders then invisibly native and not like a tourist at
all. People who don huge colonial straw collie hats with 'I Luv Lagos'
on them in Nigeria, or fat solicitors from Tonbridge on holiday in
Malaya who insist on appearing in the hotel lobby wearing a sarong
know what we're on about.
