This was covered by the 20031112 entry in /usr/src/UPDATING. As a general
rule, you should use GENERIC instead of a custom kernel configuration (or a
GENERIC config from a previous release) when updating, at least on branches
that aren't marked -STABLE.

I believe the rationale was that no -STABLE releases after FreeBSD 4
used the old statfs() interface. I agree that the name is misleading.
