It'll converge somehow. The important part is the basis of cryptographic identities i.e. public/private keypairs.
Everything else are superficial differences. Once tke keypairs are there you can easily convert between formats.
You can even link separate identities from different ecosystems even with different key algos (e.g. EcDsa vs. EdDsa) via certificates a.k.a. nostr "delegates".
