We've been solving this problem for the last 30 years without
introducing a new kind of "set before mode", so I don't understand
your example.
If `org-thingamabob-mode` is a major mode, then it starts with
`kill-all-local-variables`, so either you mark
`org-thingamabob-syntax-version` as persistent-local or you're screwed
from the outset (you can try some convoluted hack using
`change-major-mode-hook` but it's gonna be ugly).
OTOH using `:after-hook` or `hack-local-variables-hook` works right now
without very much effort.

So: delay the expensive part. It's usually pretty easy, and most of the
time it's a good idea for all kinds of other reasons.

Ah, I see. My intuition is YAGNI but I haven't thought too much
about it.
