Any idea if the airport staff has gotten more strict with the elite security lines due to the lengthy regular lines?

In the past, the airport staff has not paid a tremendous amount of attention to Silver vs. Gold/Platinum when letting folks into the lane, and has allowed elites from other airlines than those specified on any given concourse's signs.

Have they tightened up as a result of my presumed influx of people attempting to use the elite line?

Thanks.
