What do you think about this?
perhaps we should add a section about
electrodes.tsv
to the MEG section of the BIDS specification, and make corresponding schema adjustments.
I see that you have opted for not adding a new section and instead adding this information under Recording EEG simultaneously with MEG
. I think I'd be fine with that as well.

as outlined in #1550 (comment), I think this should be optional --> this electrode information can also be stored in _headshape.<ext>
files or sometimes in the data file format itself (Elekta/Neuromag/MEGIN).

IMHO the SHOULD should become a MAY.
So far, the spec allowed for recording electrode positions in the _headshape

Fixes #1550.
