I doubt that. We've all been tolerating the risk of index scans
returning wrong results in some cases.
Consider:
a. Some user creates an expression index on NORMALIZE(); vs.
b. Some user chooses the builtin "C.UTF-8" locale and creates a partial
index with a predicate like "string ~ '[[:alpha:]]'" (or an expression
index on LOWER())
Both cases create a risk if we update Unicode in some future version.
Why are you unconcerned about case (a), but highly concerned about case
(b)?
Neither seem to be a pressing problem because updating Unicode is our
choice, so we have time to reach a compromise.

Then go to the other thread[1] and propose that it be exposed as a
packager-facing option along with any proposed Unicode update. There
are other potential compromises possible, so I don't think this 17
subthread is the right place to discuss it, but it strikes me as a
reasonable proposal.
I sincerely think you are overcomplicating matters with version 17
procedural motions. Let the community process play out in version 18
like normal, because there's no actual problem now, I see no reason
your objections would be taken less seriously later.
