I go on asking questions if you don't mind ;)

Wouldn't it be more in-line with the initial idea to introduce a `ZTIMER_NSEC`, which is based on `ztimer_periph_ptp`? Timers with lower frequencies (`ZTIMER_USEC`, `ZTIMER_MSEC`, `ZTIMER_SEC`) can be sourced from `ZTIMER_NSEC`. Even `ZTIMER_SEC` should have its overflow at `UINT32_MAX` if everything is setup correctly.
