Consider the profound question, 'How do we get there from here?'. Taking into
account how long it took to produce 62386-1 from two former standards ('how
long' is indeterminate, because it’s still being improved), how long would it
take to turn the 111 standards in 60335 into one? Answer in centuries, please,
to one dismal place.

I agree with Rich that is one of the problems, and I would add that it is the
main problem with the proliferation of product-specific standards.
If the principles of product safety (shock, energy, mechanical, chemical) are
universal, then it should be possible to write 2 or 3 generic product safety
standards covering a wide variety of electrical equipment. Or,
product-specific standards could make (or should have made) extensive use of a
reference document, as does IEC62040-1 for example. In that example, 60950-1
is the "RD".
Thoughts?

In electrical part and charger, should we apply EN 60204-1 or EN 60950-1 and EN
60335-2-29 or EN 61558-2-6?
This is one of the problems of product-specific safety standards.
In 1961, James J. Gibson postulated that injury was due to an energy source
impinging on a body part. We wouldn’t have this problem if our standards were
based on energy sources such as electrically-caused thermal energy and
resulting fire.
