The cool things are not as much about what will stop working but rather
the rationale for that.

Issue 4800, the patch stopping the first form from working, is not
technically necessary (and will likely be committed at a later point of
time as the issues inspiring it).

Its main motivation was to keep

violin2 = { c d }

flagging an error even with issue 4798 since \violin2 would still
not work.  But

violin.2 = { c d }

will work, as will \violin.2 (as of issue 4797) or \violin.#(+ 1 1)
