prisma deploy looses comments. Is there an issue for this? I did not find an issue.

here's a relevant feature request: https://github.com/prisma/prisma/issues/2152.

Thanks. Do you know if they are working in it?

We are currently not working on this. There hasn't been a lot of discussion around this feature lately, maybe you could add your perspective on GitHub? If you share a specific use case that show cases why this feature is important to you, that would be of great help.
