Yes, I've heard too many ultimatums too. However, this is not simply an efficiency issue. Emacs currently does not run on FreeBSD arm64 because of the unexec problem (Bug#24892), and it's quite likely that the set of platforms where Emacs does not run will grow as platforms change memory management techniques. We should not reject a working fix merely because we hypothesize that there might be a better improvement that someone might implement later.
