For the first, it would prevent tuples corresponding to valid UTC
times (or local times) causing an exception in the datetime
constructor.  I don't have any specific use-cases, but it's not hard
to imagine passing a tuple from some external UTC-supporting source to

The second relaxation (allowing 24:00:00) comes from ISO 8601, but I
don't really know how widespread its use is.  I admit I don't find
this one particularly convincing;  perhaps Masklinn can expand on why
it's useful.
