This shocks me, what sort of issues do you hit?

+1 on this. I've been using Go almost exclusively for the last 5 ish years partly because this sort of thing never happens.

You lucked into the period when they solved the issues. If you need to work with older projects and can't easily convert them, you're going to have a bad time.

I open up random Go projects from a decade+ ago every week with no issues.

Lucky you, then. I open them every week too, but definitely not without issues.

Mainly weird issues of incompatible dependencies, maybe sometimes something that won’t compile because it’s missing a system dependency? I also feel like it sometimes pulls a newer or older dependency that is the missing some used module.
