It's possibly longer; but I don't have a large enough sample to say that 
it's safe that far back.

Don't feel the risk needs to sit on you as subsystem maintainer.
If something does come up caused by this I'm happy to help come up with 
a solution.

And if there was a regression caused by this having 
rtc_cmos.use_acpi_alarm=0 to restore the old behavior would help a

My apologies on the preempted ping.  Of course you have your own priorities.

I mostly wanted to make sure it didn't get lost during the merge window. 
  I do see that you have a patchwork [1] that you actively use so I'll 
refrain from pings in the future on any submissions.
