Actually, it need not be that complex:
SUBSYSTEM=="rtc", DRIVERS=="rtc_cmos", SYMLINK+="rtc"
This would preserve the "CMOS RTC is /dev/rtc" behaviour from previous
kernels, any additional RTCs wouldn't be linked there - but unless I'm
misunderstanding this, the kernel never had a /dev/rtc for those before
anyway.

After talking to upstream, I'm convinced that anything fancier should
enumerate RTC devices the "modern" way.
Preserving the /dev/rtc symlink for the CMOS driver is correct though.
