It is a reasonable take but it is not the _only_ one - I think it is arguably more reasonable to transition away from DST to ordinary "best TZ granularity approximation to zenith-occurs-at-noon" time once, and then stay (and manage) that time over the millenia to come.
I like this idea. I like it quite a lot.
But can we... uh... can we keep that as some kind of tertiary issue to solve later after we successfully stop screwing up the clocks twice every year? We don't really need to build a singular omnibus clock overhaul that will most assuredly never come to fruition, do we? :)
