Well, as it turns out, I just found out and confirmed that since IOS XE
3.12S and later, Cisco introduced a new feature called Aggregate
EtherChannel Quality of Service:

http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/qos_mqc/configuration/xe-3s/asr1000/qos-mqc-xe-3s-asr1000-book/qos-mqc-xe-3s-asr1000-book_chapter_01011.html

With this, you can now apply a QoS policy on a LAG port and it will work
with (almost) all QoS features without you needing to apply the policies
on the LAG member links. I still need to spend some more time testing
the policing side of things, particularly how the data plane is
programmed re: carving of configured bandwidth across member ports in
the LAG.

I also see some good work being done on the ASR920 platform (also an IOS
XE-based system), as per below:

http://www.cisco.com/c/en/us/td/docs/routers/asr920/configuration/guide/qos/qos-guidelines-xe-3-13-asr920-book.html#ID-1374-00000345

From what I can gather, none of this love has made it to IOS or IOS XR
boxes.

So quite pleased with what I'm seeing with Cisco so far in this regard...

Mark.
