This is the reason that seeds across desktop and mobile devices would never restore to the same keypair. This function was there from the initial messenger days and with further discussion with Maxim, we deemed calling this function an unnecessary step for generating a keypair. There are no security implications for this change as we generate keypairs the exact same way as Signal does.
The biggest downside to this change however is that if you try to restore a desktop device with a seed from before this change, that seed will generate a completely different key pair and thus a different session ID.
This will only affect users who plan to restore any device from the seed of a desktop device before this change.
