But you didn't want a build extension, you wanted a runtime extension, aka basically a dependency which isn't something Flatpak really has.

Ok, sure you want something like that for multiarch.

If you could, add some tests to https://github.com/flatpak/flatpak-builder/blob/main/tests/test-builder.sh

Unfortunately there is a ton of convention and tooling that expects `$FLATPAK_ID.json`. I don't think we should publish anything until we can actually ensure people would even be open to...

The nice way to do it is `flatpak-builder --install-deps-from=flathub build-dir com.voxdsp.Snowboarder.yaml`. It could be possible that when missing we search enabled repos for it.

Ubuntu 23.10 has 0.16.2... how annoying.

@nanonyme Sure, done.

Well, I don't necessarily like changing the intention of the argument, but also it likely won't be fixed soon. I guess I'd take a patch rewording it.

@Ayush1325 `flatpak-builder` must have a static list of unchanging sources. So you have to have an intermediate tool like `flatpak-cargo-generator` to get this list. In order for this to change...
