Capacitance, inductance, reflections, phasing, and terminations are all part of the speaker wire equation. There is no way to predict how they will interact with your speakers and amp.
I’ll trust the speaker designers’ opinions - ON THEIR OWN SPEAKERS. If Vandersteen has designed to benefit from bi-wiring, then the speakers might benefit from bi-wiring. If Dynaudio says "do not bi-wire," they probably won’t benefit from bi-wiring, no matter what Vandersteen says - after all he didn’t design the Dynaudios.
Unless the bi-wire has different construction for highs and lows, it’s unlikely that you will hear the difference. Unless you bi-amp also. But then we’re back to the active crossover question. Which may improve or deteriorate the sound you hear.
How many reflection points within cables are acceptable? How many strands is too many for capacitance to bass? One? Fifty? At what frequency, for your amp/speakers, does the surface effect go internal? Can you hear it? Does it strain the amp? Does it change the speaker response to impedance variations with frequency?
Will bi-wire sound better or worse if you change components? It will probably be different. Can you predict by reading opinions? Probably not. Can you tell by listening? Probably not without A-B comparisons. Can you A-B without a duplicate system, perfectly matched? Probably not.
Can you make a valid generalization about bi-wiring? Probably not.
