Yes, the parser now allows having keyword for method names, keyword names, and argument names. I don't think prohibiting them doesn't make much sense. So, I don't have a plan to revert them now.
It is intentional for method names and keyword names because they are allowed in Ruby. (Argument names are accidentally, in fact...)
According to recent sigs update: https://github.com/ruby/rbs/blob/master/sig/polyfill.rbs#L31 some keywords may be used as identifiers. IRR it was not possible in the old lexer/parser. Is there some official position on this and which keywords may/may not be used as identifiers.
