I'm just finishing up a rotary built with a 750w servo and Spinea TS 200
and I plan to run a trunion style setup, so when that is level wrt to the
Y axis, that's "home" imo.
I've be pondering this a bit as well. I'm thinking a Fadal style homing
system might be best (I have no real fadal experience, but I saw one on
the internet...). If the plate was manually jogged to within a degree or
so of level, lining up marks on the platen/body perhaps then a homing
sequence could be started to find the next index mark. It seems to me that
if you did the work to set the home offset fairly accurately once in the
ini file, this sort of homing should be quite repeatable.
I'm not really sure how to figure out homing without a home switch though.
I guess the home switch could just be virtual in a pyvcp panel or
something and could be pressed when the alignment marks are close. But I'm
open to other suggestions.

Since I've never put a home switch on a rotary,
Neither have I. It isn't often necessary. If I had something without
rotational symmetry I would probably use a spirit level on the part...
When I have considered doing it I have thought in terms of a
semi-circular track and an opto-sensor. (so it never takes more than
180 degrees to home)
