Sourcemaps for CJS files

Hello, I noticed that Prosemirror’s CJS outputs don’t come with sourcemaps (but the ESM versions do). Is there any way they could be added?

I know ESM is the future or whatever, but plenty of things still don’t support it (Electron), so it would be nice just to have this.

Sidenote: I noticed that x.es.js and x.es.js.map files are emitted too, but they’re not exported from packages. Is there a reason they are there?

None of the packages come with source maps anymore—it seems some of them were published with the old sourcemaps still in dist/, but that’s a mistake, and will be fixed on the next releases. The published files are plenty readable, so I’ve decided against adding weight to the packages by including source maps.
