The above examples seem to me to show that your argument is nonsense.
regex_flavor, in particular, is not about "failed experiments",
it's about backwards compatibility with a previous version that simply
worked differently. It might be that we can have a sunset provision for
backwards compatibility, but to argue that it's not important pretty
much flies in the face of most of the discussions we've had on the
topic.
I agree that the RULE system is a failed experiment and we need to find
something better, but we're unlikely to rip that out either until the
replacement has been in use for a few releases.
