Parallel-line can be excellent for power distribution and phasing

432MHz, in a wet climate, but those were short, straight lines that
are self-supporting with mostly air insulation - a completely
different thing.

Given a single dipole, multi-band antenna, parallel transmission line
is just about the only choice. The 50 ohm SWR on a one-wavelength
dipole is about 100:1. The 500 ohm SWR on a one-wavelength dipole is
about 10:1. Under those circumstances, it is no contest.

Very true... but also a *very* long way from the original question.
