Can the toPublic method add an pubkey_prefix parameter for user-defined use?

Original edition

function toPublic() {
        if (public_key) {
            // cache
            // S L O W in the browser
            return public_key
        }
        const Q = secp256k1.G.multiply(d);
        return public_key = PublicKey.fromPoint(Q);
    }

Revised

function toPublic(pubkey_prefix = 'EOS') {
        if (public_key) {
            // cache
            // S L O W in the browser
            return public_key
        }
        const Q = secp256k1.G.multiply(d);
        return public_key = PublicKey.fromPoint(Q, pubkey_prefix );
    }
