Bear with me one more time as I drill down a little and spell things out. I've realized that there may be more than one interpretation of "EoDWDM". Are you referring to:

(a) Ethernet packets in OTU frames - thereby implying an underlying OTN?

(b) Ethernet optical SFP+ transceivers with a cable connection into a transponder plugging into a DWDM Mux or DWDM OADM? (no circuit transport)

EoDWDM.

Ethernet is very widely used, regardless of the Transport technology.

In other markets, you will find SDH Transports delivering Ethernet as
well (EoSDH), although that is dying in favour of EoDWDM or just
Ethernet over (dark) fibre.
