remove non-argument about encouraging a principled approach
the convention indeed does not encourage discipline, as @andir points out[1], and at the worst would encourage haphazard changes because it makes them appear harmless, as @tazjin adds [2].

-
answer questions and incorporate suggestions
reworked the proposal to add semantics and combine it with related efforts to provide a systematic way of issuing deprecation warnings.
-
incorporate feedback and re-evaluate
prefer the special syntax approach, based on the arguments that all other alternatives would defeat the purpose of guaranteeing predictable results, which this proposal values higher than forward compatibility.

remove reference to
builtins.langVersionthis is unrelated to the proposal, as the version declaration is only relevant for parsing, and would cover all use cases of `langVersion` if we have minor version numbers
