I think it is fine to have different HKDF in initial secrets. You also have AES-128-GCM in initial which might be implemented in a completely slow and sloppy manner in order to progress to a different cipher suitable for some IoT device. It makes sense to me to follow the HKDF of the negotiated cipher for the rest of the connection. This also paves the road for future more efficient HKDF algorithms if/when they become available - although likely in another QUIC version.
