This is the hard part.
Even if you are able to show that SLUB is as fast as SLAB for all the
benchmarks you run, there's bound to be that one workload

AFAIK that bug required CONFIG_DEBUG_SLAB_LEAK, not just SLAB. That
seems to imply not
Recently a 2 year old bug was found in the SLAB allocator that crashes
the kernel. This seems to imply that not that many people are using the
SLAB allocator.
Currently we have 3 slab allocators. Two is company three is a crowd -
let's get rid of one.
