Problem is essentially resolved. I got one direct response telling me to try
configuring a pseudowire interface and using l2vpn context, then add the Po1
and PW interfaces as members. While I believe that would have worked, I
discovered the customer wasn't even using their untagged VLAN2 for anything, so
I pulled that VLAN out of the EFP and rebuilt it:
interface Port-channel1
mtu 1600
no ip address
load-interval 30
negotiation auto
no keepalive
service instance 1 ethernet
encapsulation dot1q 1,3-4094
xconnect x.x.x.x 1234 encapsulation mpls pw-class Raw-Mode-VC5
mtu 1600
!
service instance 2 ethernet
encapsulation untagged
l2protocol peer lacp
!
end
This seems to have stopped the removal and re-insertion of the member ports
from/into the LAG. I had assumed the customer was using this untagged VLAN, as
it was specifically configured on their trunk port as one of two allowed VLANs.
Thanks to all.

LACP bundles *through* two ASR920s actually work nicely.
Just LACP *to* an ASR920, and then forwarding said bundle via EoMPLS
(not individual VLANs, but "all of the poX interface") fails.
