v2 space cache is still rather new and had only recently some bug that could have caused catastrophic data corruption... so not everyone might want to switch.

Similarly,  people may want to have these filesystems mounted with older kernels, whose v2 support isn't that good yet.

But now it a) migrates to testing an possibly leaves even more systems with an unbootable system... b) with severity important, people using e.g. apr-listbugs won't see it.

OTOH, fixing the CVE is of course important, too.
