It seems like HR timers don't provide very much value at all. We should probably disable them, or at least substantially decrease their granularity.

Plan of record: disable.

I'm going to close this. I think HR timers are probably more bad than good for the web platform, but we dont have any serious plans to actually remove these, and FF is re-enabling, and there are definitely much bigger priorities for us privacy / security wise. Since this is all but guaranteed to never be acted on, im going to pull-the-bandaid-off and just close it
