A lot more people will want repeated dumping once it's known to be viable.
Baseline Emacs starts pretty fast, but starting Emacs for users with tons
of packages and starter kits and things is still painful. With a custom
dump file, all of that can go away. I've gotten a lot of interest in the
approach already.

Requiring a C compiler at runtime is a non-starter.

Not really it can't. There is no single-file distribution of Emacs.

I want to get out of the business of specially crafting executable files.
Finding the dump file isn't any additional hassle for maintainers than
finding any of the other numerous files we require today.
