I cant say for certain but i agree with this more hosts are "selling wordpress" what ive seen is "wordpress hosting" get offered with a free wordpress installation ( whoop ) and some demo content templates can be bought. I looks more like a offering a products and service that you already had access to on shared hosting in a more convenient and emphasised way.
Which works. I have seen that there are some differences in some packages but i doubt thats the driving force behind it.
