Hi
While upgrading our monolithic app to ruby 2.7, we realised that ruby 2.7 is not suppressing all deprecation warnings.
Here is the test case:
~/dev/freeagent (ruby_2_7_0 *%) $ ruby -W:no-deprecated -e 'require "json"; JSON::Ext::Parser.new("hello", {})'
-e:1: warning: Using the last argument as keyword parameters is deprecated
The warning is originating from https://github.com/ruby/ruby/blob/647ee6f091eafcce70ffb75ddf7e121e192ab217/class.c#L2054 and setting `Warning[:deprecated] = false` or `RUBY_OPT=-W:no-deprecated -W:no-experimental` does not suppress this warning.
