When it's automated we're back at square one: after few years it breaks and nobody will have any idea where the acme scripts are or how to debug them.
That could be an argument against automating anything, ever.
The solution is just like with any other automation - document it.
And if something silently breaks, would you rather the breakage is noticed within 47 days, or 398 days?
Even your unrelated question is another argument for shortened certificate lifetimes. :-)
