On my machine, camlboot takes ~3h to build. Then ocaml-4.07-boot takes
~30s. Last there is no meaningful difference between building
ocaml-4.07 using the embedded ocamlc and ocamlex binaries and using the
binaries from ocaml-4.04-boot; both ~6m.
I have check that camlboot, ocaml-4.07-boot and ocaml-4.07 build
reproducibly with ’--check’. They do.

At first look, yes. :-)
Modulo the minor comments I made, patches LGTM! Thanks.
Well, the next steps are to build ocaml-4.09 and ocaml-4.11 using the
previous ocamlc and ocamlex version, right?
Then, it implies rebuild all the OCaml packages, right? It could be
done in this core-updates cycle, WDYT?
Cheers,
