Lots of syntactic sugar came into being in the last few versions. This
particular bit has been around a while.

Add nested properties setting to \paper blocks.
Though this would have needed writing
var #'prop #'prep = ...
instead of
var.prop.prep = ...
at that time. The availability of the latter syntax was probably an
unintended side effect of

Allow property and grob paths to be constructed from strings
This allows use of either
\override Accidental color = #red
or
\override Accidental.color = #red
(in addition to existing forms), both for context modifications or for
property overrides in music, the latter with optional leading context
spec defaulting to Bottom. . The same holds for reverts.
which would peg this as 2.17.6 (quite later than I would have thought).
I think that this assignment-level syntax only got formalised later on.
