archiver VS go.uuid

archiver is also a very cool tool. I think its cli is somewhat similar to this.

https://github.com/mholt/archiver has a lot of helpers. Probably a good place to start.

The next major release, v2.2.0, is out now. Most notably, this release replaces mholt/archiver with a custom zip extractor for faster directory receives and smaller binaries, adds settings for controlling advanced wormhole client options and a lot of smaller bug fixes. This release also incorporates the initial support for building on Apple M1 computers (release binaries for that architecture are currently not available though).

Something to note is that all of this is still open source. Theoretically, someone can decide to fork SQLBoiler and add all the missing things, or send in a PR. A good example is that the current most popular uuid package. gofrs/uuid was forked from an unmaintained previously popular package.
