Totally agree.
I built a dipole one time and fed it with the 450 Ohm window line
everybody likes to use.
I twisted the ends of the window line and crimped a couple of terminals
on the ends. If it was going to be a permanent antenna I would have
soldered it.
Two years later when I took it down I disconnected the window line from
the 1:1 current balun and the terminals came off in my hand. Apparently
when I twisted the strands before crimping the connectors I removed some
of the copper. The steel wire underneath had rusted to dust a good six
inches back. No more window line here, doesn't matter who sells it, and
no more copper weld.

Copperweld is "nasty" stuff IMHO. If you can support it so it will
not flex, you can tension it greater than plain copper. But it
'remembers' the coils it had on the wire spool and will spring back to
those coils if allowed to remain free and untensioned. If you pull it
while it has a kink in it, the game is over, that kink will become a
spot for failure.
