I agree with you for a middle or high school level course, but I would hope a teacher could wrap their heads around a 5-7 year old level explanation of algorithms if they're capable of teaching math.

Based on informal asking, most teachers who are supposed to be teaching fractions cannot figure out whether 2/3 is bigger than 3/5 or vice versa.

Given that fact, I am not optimistic about what you hope.

If that's the case, I don't believe dumbing down the curriculum to the lowest common denominator of teachers is the solution to the problem.
