I would have thought that the danger of plastering over was obvious.

'tis thats why the regs state that wiring should only run vertically and
horizontally from a fitting (with exceptions for corners and ceilngs).

And your idea of putting the wire in plastic conduit would make not a
scrap of difference if someone decides to nail into the wall. Steel
conduit, yes.

The industrial round steel pipe conduit, yes but not metal capping. How
do you fix that? With nails...

Do you remember the very old-fashioned close-jointed "tin-whistle"
conduit? This was about the same gauge stuff as capping, but just
rolled round into a pipe. Tee-pieces, elbows and so on were attached
using setscrews. The pipe was terminated with a rubber bush.

Although it gave rather minor protection to wires, it was still
convenient for "cut and draw" replacement of wires, although it was
typically only about ½" diameter. A 1.0 sq mm T+E went through
nicely!

Early c20, I would think. When I rewired my parents' 1902 town house
(about 30 years ago) there was a lot of this about.
