Well, you can ask EDB about this, but perhaps the have kept the same ICU version so indexes will not need to be reindexed.
Correct - updating ICU would mean a reindex is required following any upgrade, major or minor.
I would really like to find an acceptable solution to this however as it really would be good to be able to update ICU.
It certainly couldn't and shouldn't be done in a minor.
But doing so in v13 doesn't seem entirely unreasonable, especially given that I believe we will detect the requirement to reindex thanks to the versioning, and not just start returning invalid results (like, say, with those glibc updates).
Would it be possible to have the installer even check if there are any icu indexes in the database. If there aren't, just put in the new version of icu. If there are, give the user a choice of the old version or new version and reindex?
