Raspberry cuttings run serious risks of transmitting various cane
diseases
including viruses, we always burn raspberry pruning's whilst nearly
everything else goes through the shredder.

So nobody's attempted softwood cuttings, then? As for virus transmission,
surely it makes no difference what method of propagation you use as a
virus will affect the whole plant regardless of which part of it you use
for propagation. Stem cuttings are no more likely to be a source of viral
transmission than root division.

Why I attempted stem cuttings is that I bought new plants last autumn
which I had pruned in early spring. I planted the prunings in soil and
their buds began to shoot I thought when theese were 2 inches long that I
could get extra plants early on from these shoots which would fruit by
next year if they would root promptly. All the cuttings I look are still
alive, healthy and have callused, but so far no roots

I would still not plant any cuttings produced plants whether or not they can
produce roots, there really is too high a risk you will end up with major
problems, and yes some viruses can effect just stems as can some
pest/parasite problems and many diseases. Cane fruit is so prone to problems
that I think it is still the case you need a certification of clean stock
from Defra to sell it officially.
