Yes I can vaguely remember the days of changing the coolant before and
after winter. Did early anti-freeze cause problems if it was left in
all year round?

Yes. It caused corrosion, and early blocking of the radiator. When all
aluminium engines became common, they produced a new version that
inhibited corrosion.

It's said to be a reason the production run of what is now the Rover V8
was so short in its original US Buick form. US owners weren't prepared to
pay the extra cost of a corrosion inhibitor.
