I'd be very happy to contribute.

Good question. That's a decision for this WG to make. Adding JSContact as an 
optional extension would be straightforward: making it the default would 
essentially create RDAP 1.1 which is a somewhat more complex proposition.

Unless we define a way to know an RDAP server's capabilities in advance, the 
client has no way to find out except to send a query and see what it gets back. 
As a client implementer I'm fine with this: some servers will support jCard 
forever so I need to continue to support them (even if only as legacy code). 
Some will immediately move to JSContact. Some may offer both in parallel, 
especially during an upgrade period, as we have seen during the migration of 
EPP from secDNS-1.0 to secDNS1.1.

If we need provide a way to know in advance (I'm not sure we do) then we could 
(a) alter the structure of the bootstrap file, (b) use server specification 
mechanism as you outlined at the ROW in Bangkok[1], or come up with some other 
mechanism (maybe by specify how the OPTIONS method can be used with RDAP?).

Alas I will not be present but will try to join remotely if possible.
