Hi Fabian,

Let me start by thanking you for the work going into packaging rustc.

rustc 1.70 was released on June 1 and made it to unstable in September.
We're now 7 months later.

At the time rustc 1.70 was released, unstable had... 1.63, which was
released close to a year prior, at which time unstable had... 1.59.

"rustc somewhat current in sid" might have been true in the past, but
that has unfortunately not been the case for at least two years, now.
I'm not discounting your work, merely stating the hard truth.

The sad part is, as you noted, the more outdated the version in unstable
is, the worse it gets to update it...

And by end of May, we'll be close to the upstream release of rustc 1.79...

Is there anything we can do to make things better? Presumably, the
src:cargo merge should help here, at least a little (because cargo being
outdated has also been another source of recurring problems).

At least for firefox, I managed to relax the rustc requirement back to
1.70, so the urgency is slightly less severe at least for that package,
for now.
