I perceive that the whole thread is about all comparison operators with one float and one decimal operand currently producing an exception (3.x)

Not true for equality comparison. That returns False regardless of value, just as order comparisons return what they do in 2.x regardless of value. I claim that the former is at least as bad as the latter for numbers.

or a type-based ordering (2.x).

3.x mixes type-based and value-based equality testing for Decimals and other numbers.
