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.
I support 0ver, my open source project is currently at 0.1.9 - I’m looking forward to releasing 0.1.10 as I continue to avoid the precious 0.2 mark when I become feature complete and open the project up to a wider audience. I assume 0.3 will be a full source rewrite when I achieve Google Scale.
