Would it be appropriate to mention that for most applications, the best
reasons to not have 90 degree angles may be outside the realm of Signal
Integrity?

And herein lies the arguement, I believe.
Perhaps those who argue against "right angles" envision a
geometry where the line has a squared corner both on the
inside of the elbow and the outside.
I would wager that those who claim no material effect are
working with the usual CAD system/photoplotter geometry of
a squared corner inside the elbow and a radiused one on the
outside.
