There are a few different on-chain implementations of secp256r1 signature verification for use with passkeys, my favorite of which is demoed at https://p256.alembic.tech

Work is also being done on SNARK-based cross-curve signature verification

But I fully agree, especially with the growing popularity of account abstraction, the EVM desperately needs a secp256r1 precompile!
