You don't have to use amp sims any more, at least not with VST.
There is a free convolution VST - PULSE by Rosen Digital Audio -
and you load up an impulse response of your favorite amp and go.



from a technical point of view, if that is literally an IMPULSE
RESPONSE, I don't see how an impulse response can define the sound
of a guitar amp.

an impulse response captures the linear characteristics like
frequency response and reverberation, but does NOT capture non
linearity characteristics like clipping and distortion.


No, you use other things for that.

Non linearity is obviously an important part of a guitar amp sound
and is not captureed by impulse response.


While that's true, there are lots of other ways to
get nonlinearity. Pedals for one, waveshapers
for another. FuncShaper does well and is also
free.

Perhaps they are mis-using the term impulse response.


Nope. It's a deconvolution and that's by definition an
impulse response.
