What design error?  float.__mod__ works perfectly.

49.0

It's only Decimal.__mod__ that's inconsistent.  float.__mod__ has the
usual floating-point inaccuracies, but then with float that goes with
the territory.

I've had occasion to use it, and it was a pleasant surprise that it
"just worked", so I didn't have to go to the math module and ponder
over the difference between modulo or remainder.  float modulo is
useful, consistent and intuitive; -1 on removing that.
