Yes, but having a proper ethernet on the edge connector would avoid the need for an RJ-11 and allow integrating a switch on the board hosting the CMs and prevent the usual mess with cables forming around the boards.
At least, that's what I'd hope.

In general, the CM has a lot of support for I/O that is just not feasible with the package the regular PI uses. Things like the extra camera and display ports can be useful for computer vision packages, but would make routing on the normal board real difficult. By minimizing the extent of the breakout, they really do make the chip able to be considered in a lot more use cases.
