Can't you just handle those "by hand"? I agree, that's what I used to do as well and this never caused me any particular difficult. The rare cases where the script emits no ID just have to be dealt with manually. It used to happen less than once per series (with series containing ~1k input patches). I'd say that the amount of failed backports is roughly in the same order of magnitude as the ones that could be missed this way, this needs to be put in perspective! > > So what I'm asking is for single, easy to parse format.

Plus this adds some cognitive load on those writing these patches, which increases the global effort. It's already difficult enough to figure the appropriate Cc list when writing a fix, let's not add more burden in this chain. > The phrase "perfect is the enemy of good" or something like that applies > here.

I find it important that efforts are reasonably shared. If tolerating 1% failures saves 20% effort on authors and adds 2% work on recipients, that's a net global win. You never completely eliminate mistakes anyway, regardless of the cost. Willy
