I think I'm with Kyle here, leave rawhide always debug and go split at branch time. Competent bug reporters will happily grab kernel-debug if required, perf people won't test until branch time most of the time anyway, I suspect. Less people running a debug-enabled kernel without realizing it (eg, F14 base kernels up until earlier today) could help SNR too.
