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.

AFAIK, no. There are some helper frameworks [1], but none of them is dominant. Two possible reasons: it's quite easy to write a (web) service with the library functions (it even includes a gzip stream), and it's practically impossible to write an ORM framework like you have in Java and Python, so the Go frameworks I've seen are basically a bunch of helper functions.
