Apparently Minification was removed in v15, I would like to bring it back. Thank you

Non-Goals

No response

Background

I am dealing with a bug in next.js production build that doesn't happen on local.
Since the underlying code is still different even when using SourceMaps, I suspect that one of the things causing it might be the minification and mangling, even though the particular thing I am relying on is not mentioned in the swc documentation https://swc.rs/docs/configuration/minification.

On that page I read that swc can be configured via .swcrc, but I read in this discussion thread #30413 that .swcrc files are not supported. But then I found out in Next.js docs that the flag for minification was removed in v15 https://nextjs.org/docs/architecture/nextjs-compiler#minification

Proposal

Same as the previous flag for disabling minification

• When the flag is present and set to true, the build output will resemble the original code.
