[banachtarski]

Oh so like, dual quaternion skinning, spherical quanternion interpolation, matrix multiplication, vector sums, etc.

I use a ton of linear algebra, vector algebra, and grassmann/clifford algebra at work and not having operators is like... why would I ever do that to myself. You end up in "parentheses" hell for things that would actually be nicely coded in concise and easy-to-understand expressions.
