Not sure if the switch is less expensive now because I haven't been keeping up with processor tech to that degree. FP in the kernel was (is?) disabled by default. Calling FP routines when the processor isn't there causes an exception, that can cause real problems in the kernel, e.g. unhandled interrupts.
