Okay to install CWM Recovery on Galaxy Nexus 3 GT-i9250M?

This article is very explicit that installing CWM recovery is only for the GT-i9250 and that the:

process here is not for other variants of Samsung Galaxy Nexus, like: GT-i515, GT-i516, GT-L700, i9250T, etc.

However this post says:

There are no hardware differences, just tweaked software (specifically Radios)

Is there any real risk to installing CWM Recovery on the GT-i9250M?
