will there be an official attitude (faq entry etc.) on that "although
we think that ULE is ready and recomended for XYZ we stick with 4BSD
for 7.0R because ABC". I think such a thing could help marketing 7.0R
when it comes out as people who might benchmark it (with GENERIC kernel)
will know that switching to ULE is the way to go but we want to be 100%
sure before making it default.

I think it would be beneficial.
