with Go 1.26, these will be deprecated:

https://pkg.go.dev/crypto/ecdsa@go1.25rc1#PrivateKey.D
https://pkg.go.dev/crypto/ecdsa@go1.25rc1#PublicKey.X
https://pkg.go.dev/crypto/ecdsa@go1.25rc1#PublicKey.Y

the issue is that if I want to avoid deprecated items, it will be impossible to do Elliptic Curve Arithmetic. this is needed for example with ElGamal ECC:
