The project won't be building non-free binaries and ship those to
people. It's the users who will do it on their machine.

No, that's not the case.

They are needed since not everyone wants or needs a full-featured
ffmpeg with all third-party libraries. There can be sane defaults,
like there have been for years, and some libraries can be enabled
optionally.

That is not correct. The following options/dependencies are not
present in Homebrew core:

chromaprint, fdk-aac, game-music-emu, libbs2b, libcaca, libgsm,
libmodplug, librsvg, libssh, libvidstab, libvmaf, openh264, openssl,
srt, two-lame, wavpack, webp, zeromq, zimg
