Well, if you insist…

For some reason this comment doesn't show up in the shorter bug URL
that you posted originally — it is linked from here:
https://bugs.launchpad.net/ubuntu/+source/hdparm/+bug/172287
So unless Tails runs a smartctl daemon (Liberté does — and note that
you need to be careful for smartctl to not wake up drives from standby
when it decides to poll them), -B254 can be problematic as well. Note
also that -B255 is still problematic for some drives — I remembered
that it was so previously, but wrongly figured out from a special case
for 255 in hdparm sources that it was a fix for the issue.
The problem is that -B254 will probably prevent drive spindown for
most people, so it's a tradeoff, and I don't think that one or even
several reports from users warrant turning power management off,
especially for a live distribution that does not require a hard drive.
Those users should file bugs against respective kernel modules. People
probably experience issues due to wireless power saving, etc., as well
— there is no one setting for any device that makes everyone happy.
