To recap, darktable ships an embedded copy of LibRaw with the following
patch applied:

It seems libraw upstream doesn't want to apply this patch (although I
might misunderstand what Pascal writes there), and darktable won't work
(or at least loses some functionality) without it.

We _could_ hypothetically ask the debian libraw maintainers to apply
this patch, but I could certainly understand them not wanting to do
something that upstream is explicitly declines to do.

I don't see an obvious way forward; some motivated person could pursue
this with libraw upstream I guess.

I think having up to date versions of libraw in debian is less of a
problem, since it is fixable by e.g. NMUing if it becomes a problem.

I have put the Debian libraw maintainers in copy, in case they have any
