What I meant in the v2 discussion is that we can see how the patch series from
Gary [1] goes and once landed base this fix on top of it, so we can avoid an
intermediate (conflicting) solution.

If, for some reason, [1] does not progress as expected, we could still fall back
to using as_slice_mut(). So, given that this fix is not super urgent, the idea
is to wait a bit, see how things go and then take the corresponding direction.

But don't worry, this is your first contribution and it is not on you at all --
I should have explained it better.

For now I suggest to wait a bit more, see how [1] goes and then let's follow up
on this.

Thanks,
Danilo
