Yes, and I can confirm I could use #:supplementary-groups in
service definitions. I override Shepherd with the mechanism in [1],
not with module-set!, however.

Yes, would be very helpful, especially as it's easy to get wrong.
I'm currently occupied with other things, though. As for an example:
your system configuration might do (as adjusted per previous e-mails),
with the following block ...
(essential-services
(modify-services
(operating-system-default-essential-services this-operating-system)
(shepherd-root-service-type
config => (shepherd-configuration
(inherit config)
(shep
herd shepherd)))))
replaced by ...
(essential-services
(modify-services
(operating-system-default-essential-services this-operating-system)
(shepherd-root-service-type
config => (shepherd-configuration
(inherit config)
(shep
herd shepherd-patched)))))
(otherwise no change in Shepherd is made), where shepherd-patched should
be defined somewhere in the beginning of the configuration file.
You could use your own shepherd-patched, or my shepherd-latest (attached):
