That works too, since it counts as putting the smarts in one place.

The idea is there might be 10 units of complexity that you have to code.
To the extent that you can control where it goes, I've found it
preferable to put (say) 9 units at one end and 1 unit at the other,
instead of 5 units at each end, for the reasons I described.  Obviously
the specific application will dictate some choices so you can't always
follow this pattern.

Someone else on this newsgroup suggested using CAN bus for some
non-automotive stuff.  I don't know anything about it but it sounded
interesting.

That is a niche area with specialized constraints, in my opinion.  I'm
more concerned with the typical situation (these days) that hardware is
plentiful and the constraining resource is development effort.
