That was the point I was trying to make originally. However, to be fair, the feedline loss generated by SWR is significant only where the loss is substantial enough to make a meaningful difference. At HF, particularly the lower bands, the SWR loss is, from a practical standpoint, insignificant.
However, I'm a VHF weak-signal operator, and I tend to think in those terms. Having a non-reactive load at the feedpoint is important at VHF/UHF, as feedline losses due to SWR can be significant on both transmit and receive.
