Hmm yes, my bad, that's even what you suggested in 
<https://lore.ptxdist.org/ptxdist/20210423063320.ge4162...@pengutronix.de/>…
will fix it in v2.

BTW, I like to get feedback mail as Cc into my inbox so I can keep a
simple backlog of my still-to-be-done patches in addition to the
PTXdist list mails, which go to a separate folder. (You often keep me in
Cc, but somehow not always, but I think mutt should do this by default
with the list-reply key binding …)
