No, that's not semantics. Developing raids costs money and resources. Money tends to be finite (unfortunately). Consequently, any company with half a brain will spend it into stuff that will benefit the largest portion possible of its customers, or failing that,
will take an investment proportional to the return.
Vanilla and BC raids took a lot of resources to develop but were not seen or experienced by an overwhelming part of WoW population. Economically speaking it is throwing money out of the window.
