Ah yes, sorry for not noticing!
The problem with this syntax is that currently ‘start’ procedures can
take an arbitrary number of arguments:
herd start foo x y z
means that the ‘start’ procedure of foo is passed x, y, and z as
arguments. It’s occasionally useful and we do have a few System/Home
services that use it (‘home-pulseaudio-rtp-sink-service-type’,
‘guix-service-type’, ‘documentation-service-type’ in the installer).
So I think we can’t just remove support for that syntax.
Not sure how to improve on that.
