Wrong observation, as pointed below.

Exactly.

But what you have missed is,
this applies to accelerometers,
not gyroscopes we were talking about.

Vibration structure gyroscopes alias Coriolis gyroscopes,
either macro size or MEMS size,
detects angular speed, not angular acceleration
via Coriolis force
acting on vibrating structures, when they rotate.

Good inertial navigation systems
have both accelerometers and gyroscopes.

3 accelerometres for 3D linear acceleration
3 gyroscopes for 3D angular speed
and optionally also
3 Hall sensors for magnetic field orientation.
