This is a strange way to interpret the abilities of the creatures in D&D and seems like a bit of a catch-22. Are they magical/supernatural abilities because they do not exist in the real world or are they mundane abilities for those creatures because they are just things those creatures can do? Kinda seems like you can pick whichever side of the argument suits you.It's not silent. It talks about magical/supernatural abilities that creatures get, which in the normal course of understanding shows that if you have something beyond real world mundanity, it's supernatural or magical. You don't see a creature with a dispelling strike that isn't a magical ability. You don't see a creature that turns people to stone with mundane gaze or touch. And of course the words natural, mundane, supernatural and magical use their commonly understood real world meanings.
A mundane ability to dispel magic would be contradictory to what 5e states about itself and meanings.
And I can in fact judge dispelling strike by the real world commonly used definition standards for the words mundane, magical and supernatural.
In either case though, again, all you've pointed to is an absence of evidence that mundane attacks can impact magical effects. The presence of a "dispelling strike" would be that evidence. It would not impact or contradict any of the current "dispell" interactions, it would just be one more.
