There is nothing wrong with this method *unless* the power dissipated
melts the cable over time; which can happen especially if balled up in a
container.
Power loss is usually dissipated as heat, and we have to remember not to
exceed the specifications of what is dissipating the power; coaxial
cable, attenuator pads, cavities, or whatever.
Certainly if you need to drop a 5 watt transmitter to 2 watts, then this
cable could dissipate the 3 watts as heat relatively safely.
