Is there an (official) way to override this in a sustainable way? Is

herring and am I doing something else wrong?
I figured it out! Maybe it is super trivial to everyone here, but just
in case ;-)
As Go modules are disabled when building packages, the Go version is not
picked up from go.mod and therefore the compiler doesn't opt-in to any
of the "flags", e.g. the Go 1.22 HTTP Mux patterns. The output of `go
version -m` was a bit confusing as it seemed someone was explicitly
setting some kind of default, BUT these are just the values of the flags
if you never opted in to *any* of them.
The "fix" is to patch the main.go file and add this to the top:
//go:debug default=go1.23
Then things start working as expected! :)
I don't know how to do this using GODEBUG, it seems export
`GODEBUG=default=go1.23` in the spec file does NOT work, but probably
patching it in the source code is not the worst approach.

François
