Hi Michael, I actually tried to adopt this patch into 7.10, because I thought it was needed for another dependent patch we wanted. Unfortunately, the backtrace-via-implicit-params patch seems to depend on some prior work by Simon PJ in the typechecker (-fwarn-redundant-constraints, a rather large patch), which we *did not* want in 7.10 (the *textual* diff applied fine, but there were some API changes the backtrace patch needed, so it failed to build). So, in the end, it was easier to surgically remove this patch from the one that depended on it, and it had a much lower 'surface area' of changes, than adopting both. Hope that makes sense.
Also, as Simon said, we don't normally do big changes like this in point releases, so I think this is unlikely to happen. So the short story is "afraid not". But a backport should be possible, if you're willing to get your hands a bit dirty (any conflict will likely be fairly easy to fix, but it will involve some textual munging).
