Research direction

Start by locating the attachInterrupt entry point and its implementations in the Arduino core API. Trace how the wakeup flag is set for external interrupts and determine which platforms are affected. Done means wakeup is not enabled when it is unnecessary, while existing interrupt behavior remains compatible across cores.

Written by the indexing model from the issue text.

Description

I know that it is possible to remove the explicitly set wakeup flag manually.
Anyway it would be better to not set it at all if not required.

Possibly:
void attachInterrupt(pin_size_t pin, voidFuncPtr callback, PinStatus mode, bool wakeUp=true);
