Thanks for the answer! I have a followup question: if the server is Linux, that means the app itself (or the "solution") is Linux based, which means that an OCaml solution would have to compile (or cross-compile to) and run on Linux, which means that ARM64 on Linux is relevant :)
Unless of course most OCaml devs don't target Linux.
Sure it's relevant, but again like Eduardo said, most devs don't have Linux ARM64 dev machines, they don't use it on a daily basis, they don't have experience with it.
