I have not looked at the patch so I cannot say much about it, but it
is annoying to fetch segments you are not going to need anyway if you
target recovery with a timeline older than the segments fetched and
this has a cost when you pay for the bandwidth of your environment
with only one archive location.  So a backpatch sounds like a good
thing to do even if recovery is not broken per-se, only slower.

Designing a TAP test for that is tricky, but you could look at the
logs of the backend to make sure that only the wanted segments are
fetched with a central archived solution and multiple timelines
involved.  And costly it is.
