5) There is another unspoken benefit that people wanted to get from LSF/MM (*)
and you mentioned it below that is to get the high level VFS/MM maintainer
in the room.

I think that was not always the case with Plumbers (not sure?), but if LF is
going the make sure that Plumbers stays co-located with the maintainers
summit and we "nominate" Plumbers as the official replacement for LSF/MM,
then this will probably sort itself out.

(*) I've intentionally left out BPF, because I think it always has a miniconf
of its own in Plumbers anyway.

Some of us have had to choose whether to go to LSF/MM or to Plumbers in a
given year. I know that merging them will make it easier for me.
