Hi Rod
Both were considered but on the first not all customers have the proper jack so we felt bare wire is easy for anyone to implement and once you attach the bare wire you can easily connect or disconnect the trigger wire. You can also easily parallel wires easily by doubling or tripling up the wires in the same connection.
We could have added the second set but it would have made the upgrade path from SST2 to Cubed a bit more difficult according to engineering.

Thanks James
I wasn't aware you could double and triple up on wire to each terminal so I suppose that could prove handy. I know I personally have had nothing but a hateful relationship with these triggers over the years because whenever it comes to having to reconnect, the amps are always in the rack (or another position) with little room to maneuver behind them leaving me struggling to get the wires in and screwed down. Many times I've wanted to rip the amp from the rack, etc. and drop kick it off the balcony in frustration

The jack designs are simply plug n' play.
As for the binding posts on the 7's, yeah I see where that would have been a bit more complicated. You mentioned the SST
2 back panels are being replaced anyways during the upgrades so I guess that wouldn't be the issue, that would come in when wiring up to the extra set from the SST
2's existing desgin components. To bad though it wasn't being offered an an option for an additional charge, both as an option for new 7B
3 and for upgrading the SST
2's
