Are your concerns concrete?

I have thought about and tested this already before: The three example
items above show up in the agenda, and are still correct even after
changing with `S->'. So this "newer/future" Org file format works even
with the "older/today" Org software. This is because the Org software
of today flexibly binds the special property TIMESTAMP per item to the
first active timestamp (i. e. "<>", not "[]") that is not prefixed
with `SCHEDULED: ' or `DEADLINE: '. This binding is the reason why I
would stick to the name TIMESTAMP when it comes to possibly new
features that should write this special property keyword explicitly
for this kind of timestamp. The sibling (not `C-c .') of `C-c
C-s'/`C-c C-d' that you suggested originally would be such a feature.
