I firmly agree with this. The way to implement Irish standard time is the
way it has always been implemented: it is simply the names that would be
changed to call one of them standard and one not.

I also agree with Stephen Colebourne: the focus should be on small, stable
updates, not potentially destabilizing "cleanups".
