I have never understood how it is still permitted to have a
lampholder like in the OP

Nothing wrong with them, provided they are installed and maintained
properly.

The way the lampholder is suspended depends on the grip of the actual
screw-fittings on the bare wires.

And also the strain relief channels fitted to the rose and lamp
holder. Older fittings may not have these and they may be worth
replacing.

If a moderately heavy lampshade is used then the whole thing seems to
be asking for trouble.

One should assess the maximum mass one may safely handle. There are
tables about such things.
