-	// can also downgrade to a lower version, but only if the module version is at least Go 1.21.
-	//
-	// The restriction on downgrading doesn't matter to us. All language changes before Go 1.22 will
-	// not type-check on versions that are too old, and thus never reach our analyzes. In practice,
-	// such ineffective downgrading will always be useless, as the compiler will not restrict the
-	// language features used, and doesn't ever rely on minimum versions to restrict the use of the
-	// standard library. However, for us, both choices (respecting or ignoring ineffective
-	// downgrading) have equal complexity, but only respecting it has a non-zero chance of reducing
-	// noisy positives.
-	//
-	// The minimum Go versions are exposed via go/ast.File.GoVersion and go/types.Package.GoVersion.
-	// ast.File's version is populated by the parser, whereas types.Package's version is populated
-	// from the Go version specified in the types.Config, which is set by our package loader, based
-	// on the module information provided by go/packages, via 'go list -json'.
-	//
-	// As of Go 1.21, standard library packages do not present themselves as modules, and thus do
-	// not have a version set on their types.Package. In this case, we fall back to the version
-	// provided by our '-go' flag. In most cases, '-go' defaults to 'module', which falls back to
-	// the Go version that Staticcheck was built with when no module information exists. In the
-	// future, the standard library will hopefully be a proper module (see
-	// https://github.com/golang/go/issues/61174#issuecomment-1622471317). In that case, the version
-	// of standard library packages will match that of the used Go version. At that point,
-	// Staticcheck will refuse to work with Go versions that are too new, to avoid misinterpreting
-	// code due to language changes.
-	//
-	// We also lack module information when building in GOPATH mode. In this case, the implied
-	// language version is at most Go 1.21, as per https://github.com/golang/go/issues/60915. We
-	// don't handle this yet, and it will not matter until Go 1.22.

-	// version at all is provided, which should preclude per-file downgrading. On the other hand,
-	// https://github.com/golang/go/issues/60915 suggests that the language version is at most 1.21
-	// in GOPATH mode, which would allow per-file downgrading. Again it doesn't affect us, as all
