The only version management I believe in is Nver.

I write code once and then leave the project completely. Start with 0.0.1 and end with 0.0.1

Is gmail still considered beta?

It's funny. With Go modules, though, there's a very real consequence of moving to 1.0.x; the build system starts imposing different constraints. Same with the move to 2.0.x. Changing versions means more than just throwing a tag in the VCS.

Most of the time, it's what you'd do anyway and isn't a bother. Sometimes - not often, but non-zero - it's an imposition.

To be completely serious for a moment, conventional commit + what-bump is really useful for doing semver
