My two cents go to requiring the frame to be sent immediately after the handshake. IIRC, we discussed the issue long ago, and IIRC the consensus was that clients "can" wait for the server's SETTINGS frame before sending requests. Doing so improves the efficiency of QPACK for example, assuming that the server supports the use of dynamic table.

Generally speaking, I think it is preferable to be able to learn about the capabilities of the peer at the earliest moment. OTOH, I do not think there is a compelling reason to postpone sending SETTINGS frame.
