I think the intent here was to mean "use case where there is a need for such a 
technical solution" ... correct me if I am wrong.

I.e. it is not clear to me that "ease of deployment" is synonym with "use-case 
for such deployment". Typically, for the same reasons that this WG created the 
existing profiles, legacy header compression algorithms would not be deployed 
where ROHC is expected to be deployed. If the argument is to have legacy header 
compression being deployed elsewhere, than there is no need to wrap those 
inside ROHC.

Honestly, from personal standpoint, I must admit I am not so interested in 
entertaining this discussion once more, or to keep this WG alive on artificial 
life-support ...
