Besides ~~QTBUG-116076~~, which is probably still fixable, we also have that

Expectation would be, like in the epic, that equal values produce equal hash values.

This might be fixable in Qt 6, as the double and long double overloads are out-of-line, only the float one is inline and therefore immutable.

QTBUG-116076 qHash(qfloat16(x), seed) != qHash(float(x), seed) unless seed == 0

QTBUG-116080 Inconsistent hashing between qint{32,64} on 32-bit platforms

relates to

QTBUG-116064 [REG SiC 6.4 -> 6.5] qHash(qfloat16(x)) is now ambiguous on GCC13
