Wirewound resistors are not perfect, but at least they will be stable
with temperature and power applied. The same can not be said for light
bulbs.
At 2.0 MHz, wire-would resistors might well be OK. But if they are not
good enough, tweaking them with some external reactance will be a lot
easier than trying to tweak something that will have massive change in
parameters depending on the applied power.
