Well, we're many decades on, knowledge and technology has
improved.  We don't build steam engines like they did in
1900 any more either.

Cone shaped coils don't seem to be very popular, for whatever
reason.  Perhaps they are harder to make.  There doesn't seem
to be much, if any, theoretical advantage to them.

A 'purely disruptive system discharge with no LC oscillations?'
You'll probably need to clarify what you mean by that before
anyone can answer.

Kind of.  The 'burst' consists of two decaying sinusoids,
which reduces to a single sinusoid when the primary gap
eventually opens.   Modern research into multiple resonance
networks (recent archives) approaches a more broadband type
of operation using higher coupling, in which higher frequency
resonances are exploited and the resulting waveforms are
more 'pulse like'.

I think Tesla wasn't very bright or competent compared to
others of his time.  He had plenty of imagination and vision
but lacked the skills necessary to filter out the bad ideas,
or to make a success of the good ones.   I would say he was
a master of muddled, wishful thinking, falling well short of
the 'genius' category.

If you want a genius to admire, there are plenty of first
class candidates from that era.
