What's the point in PVC channel anyway? It offers little protection.
Is it just to make thing easier for the plasterers?

Basically yes - protects the cable from trowel damage, and holds it
flat to the wall. It is sod all use later should you want to extract
and replace a cable.

I don't understand why you say it is no use later if extraction and
replacement of the cable is required. I would have thought that was
the principal advantage, please advise.

It will be ok in short straight runs, and if carefully lined up at the
entrance to a box. But life is rarely that simple. ;-)

Besides, the chances of a re-wire in some 50 years time requiring the same
cable runs are remote.
