Don't you think a Bessel function is somehow more "mathematical" than the isnormal function?

No, but that may be a function of my personal view of mathemmatics. isnormal is a set classification function, and as such has a long and important history in mathematics. It isn't what most non-mathematicians think of when they consider mathematical functions, but many very important mathematical advances that happened before the advent of computers were based around such classification functions. isnormal in specific isn't a classification rule that I expect would have been used before digital computers, but the underlying model of functions that trace what is and is not included in a set is an old one in mathematics.
