Also, one major thing I'm missing personally is automatically generated OpenAPI specifications + API documentation & API clients autogenerated from it. Last time I checked Go, you had to write the spec manually, which is just ridiculous — the code already has all the necessary info, and duplicating that effort is time-consuming and error-prone (the spec says one thing, the code does another). This may be out of date, but if it still isn't, it is enough to disqualify the stack completely for me.
Also, I don't think there anything similar in the Go world to these administration panels:
https://docs.djangoproject.com/en/5.1/ref/contrib/admin/
which are just fantastic for intranet projects and/or quick prototyping.
