Rob, I'm 100% with you.
I don't recall who wrote that line damning openwire, but he's off in
theoretical outer space.
In the practical world we live in, we have to accept compromise.
Not one in 100 hams has space for 9 antennas.
Most of us struggle to find space for just one.
I also emphasize your preference for genuinely balanced (symmetrical)
matching networks (matchbox).
And if that won't work (for instance my current QTH where I cannot install
openwire through the air), we drop down another layer of compromise and go
with an OCFD.
As the old sailors used to say, "any port in a storm."

>I do NOT recommend the use of open wire line as a band-aid for badly
matched antennas.
This doesn't change the fact that every shortwave broadcast station in the
world uses open wire line to balanced antennas, usually rhombics and dipole
curtains, for covering multiple assigned frequencies across HF.
Anyone can use coax for everything and have a dozen dipoles up to cover HF,
but decades of research, and practice based on physics support the
successful and efficient use of balanced open line with balanced loads and a
correctly designed genuinely balanced matching network.
