Laurent Bercot earlier brought up this exact philosophical reason not
to do it. You two make a good point, but I disagree with the point.

This point would be spot on if Devuan had any marketplace clout. The
trouble is, with Devuan currently having such a tiny "market share",
and Devuan having almost zero funding (compared to Red Hat, Cannonical,
SuSE), threaten an upstream with "your software won't go on Devuan" and
their response will be "so what, I'll lose 0.1% of my users". In fact,
compared to that tiny loss, Devuan will lose many more because many
user's favorite program won't run on Devuan, for philosophical reasons.

Which makes it yet harder for users to avoid systemd, creating more
systemd usership, shrinking our "market share" even more.

Bottom line: The perfect is the enemy of the good. To the extent that
shims can defuse silly, reasonless dependencies, in situations where a
revised makefile and maybe tiny changes to the C can't do it, shims
help Devuan continue to promote life without systemd, and hasten the
day when *everybody* will realize King Lennart has no clothes.
