As stated in 
https://github.com/quicwg/base-drafts/pull/2520#discussion_r265213467, I prefer to stop requiring the use of full-sized packets once the client observes a response from server. Reasons:
* QUIC stacks would have the logic to change rules based on if the peer's address has been validated due to the 3-packet rule on the server side. It's just about using the same logic for padding on the client side.
* Implementations that prefer to pad all the Initial packets it sends can do so anyways.
* Regardless of what we decide, the server side logic would be indifferent; i.e. create new connection context only when observing a full-sized Initial packet.
