 Optional properties:

According to the SP805 TRM, the default interval is dependent on the rate of
WDOGCLK, but would typically be a lot longer than that :/

Depends on the definition of "default". In the context of watchdog drivers,
it is (or should be) a driver default, not a chip default.

DT describes hardware, not driver behaviour.

In this case it describes expected system behavior. Most definitely
it does not describe some hardware default.

Please note that I do not engage in discussions I consider bike-shedding.
This is one of those. Dropping out.
