I think a good indication is also the fact that frequency invariance was
broken for a long time for bL_switcher_enabled systems and nobody
shouted.

A way to make this nicer is to fully remove BL_SWITCHER support. This
support was valuable at its time, but given that now there is proper
asymmetric CPU capacity support, is there any reason to hold on to this?

Thanks,
