Proposal Details
The internal method crypto.internal.fips140.aes.gcm.NewGCMWithCounterNonce was added in go1.24. This method would be nice to expose for users that want to use it for FIPS-140 compliance reasons.
Outside of FIPS reasons, this method is also nice because it asserts your GCM nonces are non-repeating (when you are using a counter).
NewGCMWithRandomNonce was exposed in crypto/cipher with #69981, so I imagine it could be exposed in a similar way.
