Adding notation with a different name

I happen to require to add a notation when signing a key. Which crypto.NewSigningContext theoretically permits me to do, only, the name the notation will acquire appears to be hardcoded in constants/context.SignatureContextName. With my admittedly limited knowledge of golang, this becomes extremely problematic to fix.

Why?... Is this deliberate or a historical holdover of some sort?
