Hi just throwing this idea out there.
Have you guys at Mikrotik ever played with the idea of running your own flavor of operating system on top of these Quanta/Edge Core whitebox switches or rebranding some and introducing your own product line ? We generally throw a minimum of 7-20k at HP/Dell for high density SFP+ switches at the distribution layer, and had one of those Edge Core switches on trial loaded with Cumulus.Performance was freaking terrific due to the awesome Trident 2 chipset on the switch bbbbuuuttttt
while I get the Cumulus thinking behind it , the support costs are pretty high when you add up a whole bunch of switches (10Gbit $999 ,40Gbit $1299 per year per switch) and having to deal with the linux shells instead of some wrapper/overlay takes away a lot of the user friendliness and lower end tech serviceability
I don't think it would really eat into the CCR1072 lineup because there are always things you can only do on a Router (Nat,Proper Packet Inspection/Traffic flow) that are usually unsupported on L3 Switches.
