...
While the server is allowed to perform multiple Retries, the client
should impose a limit in order to avoid being caught in an endless loop.

always use connection IDs longer than 8 bytes when sending a Retry
...
A server is allowed to perform multiple Retries. There's little to gain
from doing so, but it's something our API allows. If a server performs
multiple Retries, it must use a connection ID that's at least 8 bytes
long. Only if it doesn't perform any further Retries it is allowed to
use shorter IDs. Therefore, we're on the safe side by always using a
long connection ID.
This shouldn't have a performance impact, since the server changes the
connection ID to a short value with the first Handshake packet it sends.

use a random length destination connection ID on the Initial packet
...
The destination connection ID on the Initial packet must be at least 8
bytes long. By using all valid values, we make sure that the everything
works correctly. The server chooses a new connection ID with the Retry
or Handshake packet it sends, so the overhead of this is negligible.

This is important because we need to make sure that we can remove old
ACK ranges from the received packet history. The logic we implemented
before was not correct, since we only made sure that every 20th packet
would be retransmittable, but we didn't have any guarantee that this
packet would also contain an ACK frame.
