one more thing, consider the type of bearing used for the clutch release bearing.


And now think about it : You have 4 other , similar bearings on your car, that do WAY more work, see WAY more stress.

Wheel bearings.

How often do you replace your wheel bearings?
They last a really long time

Now multiply that time by 5 , because there's no way a clutch release bearing has even a fifth of the wheel bearings stresses on it.
You'll do a lot of driving before even coming near the issues people imagine.

At least if the clutch play and all other things are in spec , but if they aren't, idling in neutral isn't going to fix that either.
