 chance that the remote peer reaches the limit early and becomes blocked. In
 particular, the value chosen for `initial_max_uni_streams` should consider that
 remote peers may wish to exercise reserved stream behaviour ({{stream-grease}}).
-To reduce the likelihood of blocking, both clients and servers SHOULD send a
-value of three or greater for the QUIC transport parameter
-`initial_max_uni_streams`, and a value of 1,024 or greater for the QUIC
-transport parameter `initial_max_stream_data_uni`.
+To reduce the likelihood of blocking, both clients and servers MUST allow
+the peer to create one unidirectional stream for the HTTP control stream plus
+the number of unidirectional streams required by mandatory extensions (such as
+QPACK), by setting an appropriate value for the QUIC transport parameter

I went with option 1. I also agree that the TP is the best way. Also because the paragraph now starts with "To avoid blocking", and sending MAX_STREAMS is not a great way to avoid blocking.
