Probably worth running tests with Valgrind on those other versions, if
you haven't already.

We can worry about which versions it makes sense for, and we should,
but it's more important to make sure that the TRUST_UCOL_STRCOLLUTF8
idea is useful as a way of defending against a class of possible ICU
bugs. If every package maintainer applies their own patches for ICU,
which appears to be the case, then we shouldn't be too surprised if a
certain maintainer needs to go their own way on
TRUST_UCOL_STRCOLLUTF8.

Has anyone reported this to the Debian maintainer yet?
