The relevant TC39 proposal proposes debug IDs to be in camelCase (debugId): https://github.com/tc39/source-map/blob/8be0fe10ad042e13f4196d17b44ddedfd6a9df58/proposals/debug-id.md?plain=1#L111

We probably need to figure out some sort of migration path or cut a major for this?
