Sorry to have put you in a bad mood, LowLevel.
After some thought, if this guy J.C. Lawson and his group at the MEC had been better diplomats, they wouldn't have taken the attitude of shoot-for-the moon because we've got 400 DAL drivers by the short & curlies.
Inextricably linking 1 issue to their demands was pointless.

If they had just said something like, "We sympathize with our ALPA brothers/sisters at Delta, and will make every possible effort to ensure ComAir gives preferential hiring to displaced DAL pilots. We welcome the wealth of knowledge they bring...etc." --THEN-- go to the Delta MEC and say, "now let's talk about this SCOPE, blah, blah..."

Hell, the MEC doesn't decide who gets hired, so make the company shoulder being the bad guy by demanding seniority resignations, or training contracts, etc.

BTW, your thoughts about SLI's and what happens if a wholly owned gets sold are right on! Which is why flow-through agreements are the only way to go...unless you're a lifer Capt. at ComAir when they flow-back...guess who runs ComAir ALPA?
