Ok, but do darktable really _require_ newest version of libraw?

Indeed. A diff between upstream LibRaw and the convenience copy shipped
with darkroom reveals these 3 lines of difference:

Even if upstreams could not be persuaded to carry that change, it does
not seem unlikely to me that Debian maintainers of libraw might perhaps
be convinced to include a patch that added above as an ifdef which
darktable could then make use of - if it does not turn out to be
harmless to include in all cases (I don't know the code well enough to
judge).
