I would hope it is both. Some changes simply cannot become current
practice since they would not be compatible with existing code, and
the only place that such changes *could* be made is in a new language
version. Like you say, fail in the Monad class is one such issue that
would not be backwards compatible, and couldn't become a current
practice without some help. Chicken or egg first?
