Sorry I'm a bit out of the loop & probably missing some context here.
I think I'd prefer to keep the personal names in ERC's Maintainer(s)
field if possible, but if it's too much of a hassle and/or impossible
then of course that's a different story.  I'll defer to J.P. and you
to go forward with whatever works best.
