OK, enough people have pointed it out :-).

Clearly I was wrong about the MX 2K family, I missed the SFP+ MIC completely.  That is good to know.

However, the MX 10k family still only shows as being compatible with two QSFP cards.  And yes, you can get a QSFP-SFP+ breakout cable, but those don't let you use SFP+ CWDM/DWDM transceivers.
