The -go flag causes tidy to update the 'go' directive in the go.mod
file to the given version, which may change which module dependencies
are retained as explicit requirements in the go.mod file.
(Go versions 1.17 and higher retain more requirements in order to
support lazy module loading.)

The -compat flag preserves any additional checksums needed for the
'go' command from the indicated major Go release to successfully load
