Now we have a temporary solution https://github.com/browserslist/browsersl.ist/pull/435

The idea of the solution by @ai https://github.com/browserslist/browsersl.ist/pull/435#issuecomment-1218990106

• [ ] Copy of algorithm https://github.com/browserslist/browserslist/blob/main/node.js#L285-L294
• [ ] Preserve \n in URL so the multiline config can be copied by URL
• [ ] Support comments

+1 for this, our browserslist config has comments inside, and when we copy-paste it as is comments are treated like queries.

Is it in progress (with a bigger refactoring), or PRs are welcome to fix comments at least?

@AleksandrSl no, it is not in a progress and PR is welcome
