Desert Temple TNT trap may detonate prematurely

There is always the possibility that a mob spawned in the low light levels inside the temple where the pressure plate is. If it walks on the plate, the trap will trigger.

Gotcha. That's somewhat likely too since I'm on peaceful but have spawn-monsters on so they blink in and out of existence like crazy.

Have Mojang ever explicitly confirmed this to be intentional game design?

For general reference, the resolution of this ticket has been reviewed by Mojang and left unchanged.
