1U routers that support 25G have been on the market for a little while 
now. I don't think this is the issue.

What has been lacking is a Layer 2 25G demarc. box, and Adva are just 
about the only vendor who have had one for some time, as the OP mentioned.

Outside the data centre, the primary customers for 25G has been mobile 
operators. With 100G-ZR+ coherent now starting to ship from next month, 
I suspect this will put 25G RAN backhaul under a bit of pressure.

I do think that for Metro-E services, there is a use-case for 25G, 
especially now that cheap, Broadcom-based routers are shipping with 25G 
ports. I'm just not sure plenty of MEF-compliant Layer 2 demarc. options 
exist outside of the Adva number.
