I also have noticed this new 'toolchain' option. I'm a bit confused about how it works.
"This automatic toolchain switching can be disabled, but in that case, for more precise forwards compatibility, the go command will refuse to run in a main module or workspace in which the go line requires a newer version of Go." Can someone explain how to disable this? I never want to download anything at compile time. I'm also sure there are a huge number of real reasons why that is not acceptable. Is it acceptable to never publish a "toolchain" option in the go.mod file or is it required? If it's not going to be required, I will just remove it from all of my go.mod files before I publish them.
