Yes, most of the activity has been on the github repository:

If segwit doesn't activate, something is badly broken in Bitcoin. This
is not really a lightning issue; there's been no significant technical
objection to segwit, and it really does make Bitcoin work better.
I'm glad that miners are cautious with their upgrades, and segwit
adoption will take time to roll out across products anyway. Let's look
again in 6 months.

Yes, the problem is outsourcing. You can't hand the outsourcer a
penalty transaction signature if you don't know what the bad transaction
will look like. And if the signatures are part of the transaction ID,
Hope that helps,
