Re: [w3c/manifest] Don't use enums, because they throw (#633)

The problem is that we already have thousands of manifests in the wild that are depending on the fault-tolerant behavior.

I'm not sure that is true. In Gecko, we don't do any IDL conversion. Additionally, It's too much work to have a custom IDL implementation for this or other formats. It's just not a viable thing.

This doesn't sounds like it would lead to very interoperable behavior.

Probably :)
