Since upstream hasn't made up their mind yet, I think it is preferable
to revert the version in unstable to the last known good version. From
my understanding that is 2.9.14. We can then revisit this transition
when upstream decided how to continue or the transition freeze for
trixie comes close.
libxml2 is a core package where proper handling of the ABI is essential
for us. The time until the transition freeze is hopefully enough to get
some decision with upstream.
