I don't think I follow: why would this be impossible for subsequent dumps? Maybe I should describe the use case this is supposed to solve. Imagine a repository where Emacs is being built regularly, and where old Emacs builds are kept for long periods of time, together with their *.pdmp files. So we will have emacs-28.0.50.1, emacs-28.0.50.2, ... emacs-28-0.50.1000, ..., and their respective *.pdmp files. The intent is to be able to run these old binaries for quick "bisecting" of issues reported by users. This is what I do on my system: I keep one build from each of the previous months, and delete the rest. Until native-comp, keeping the binary and the .pdmp file was enough for being able to run that binary. With native-comp, we also need the *.eln files that were dumped into each of the *.pdmp files. I'm trying to find a reasonable solution to this problem.
