That's a clear "no".

Preset files shall never be shipped by their own packages. That defeats
their point.

If you have a unit file that you are sure should be unconditionally
enabled, then enable them via a .wants/ link /usr, rather than in
/etc. But really, we do that for very few services only, and we
shouldn't do that for timer units either really, as that only leaves
masking as a way for the admin to disable these units.

I am pretty sure the Also= link in a service units' [Install] section is
the best way to go for most packages.
