If you fly a conventionally-controlled aircraft, this is a good reason to apply forward pressure on the control column for the early part of the take-off roll, and make a point of feeling the column move when you relax this pressure (at 80/100kts or whatever the manual says). This provides some confidence in the state of the controls for the early part of the take-off roll, and the statistical risk of control failure in the short time between that speed and V1 is lower than that from control checks to V1.
