I tried it on a desktop machine for a while and noticed no
tangible differences.

from /usr/src/sys/conf/NOTES:

# SCHED_ULE is a new scheduler that has been designed for SMP and has some
# advantages for UP as well.  It is intended to replace the 4BSD scheduler
# over time.  NOTE: SCHED_ULE is currently considered experimental and is
# not recommended for production use at this time.

AFIK, you cannot have both SCHED_ULE and SCHED_4BSD
in the same kernel, which is likely why it is not yet in GENERIC.
