Is there any (spec) reference we can link here?

And the 2h5m would be on top of the previous max_wait, AFAICT.

And, didn't we already fix something like this? Or at least had some
other handling added for long initial initialisation of LTO9 tapes, or
was that something different or just a discussion without a patch.
Not really important though, just wondering.

Changes look alright besides of those meta things, so I could fleece
any relevant info into the commit message too on applying, if nothing
else comes up.
