1) apparently it's not mandatory in CoAP (I thought it was until a few
   minutes ago).    We can save ~15 bytes here.

2) The proxy knows where the JRC is because it's been told the IP address of
   the JRC, either implicitely (it's the DODAG root, aka 6LBR), or
   explicitely via the response.

Remember that we can type https://[fde4:8dba:82e1::1234]/ or, in this case,
we want the pledge to say: coap://[fe80::1234]/j, which the Join Proxy
forwards to coap://[fde4:8dba:82e1::1234]/j (of ourse, using OSCORE).
