Yes they don't break off the wire as you tighten it.

Could have been. I use those now, but dunno about 30-odd years ago.
They're good though, in my opinion.

I had a batch of the ones without the metal 'tongue' and they cut the
wire even before you'd really tightened them. The screws had circular,
sharp, 'flash' around the bottom.

Quality, eh?

I think the idea was to 'spread the effect' of cold welding. The big
flaw was that it was all too easy to overdo it (plus there was no
'spring applied pressure' that would maintain the contact pressure
through thermal cycling).

These ones I had were unusable. Any reasonable tightening would start to
cut the wire, then if you moved it strands would pop out.

Yes, I'm familiar with those, but I don't agree: you are being too
generous! I'm almost certain there was no "idea" to it, merely crap
manufacturing.
