I don't agree with this - experimental means (outside of exceptional cases)
it is unsuitable for production code because it may be insufficiently
shaken out or require breaking changes or get removed entirely. Core can
adjust in tandem with the feature for the latter issues, but not the first.
That doesn't seem suitable for code shipped with Perl which is not itself
experimental. At the very least, it should require case by case
determination on whether the particular feature is appropriate to use in
the particular module.
