With small signal triodes, grid current can vaporize the tiny grid wires. That's why on stages designed for significant clipping large grid stoppers are used to limit that current.
To get the most out of power tubes, many are designed to tolerate a certain amount of grid current. I believe the KT88 has a 2W limit on the power that the grid can safely dissipate.
When setting up power tubes for A2 or AB2 operation there are a number of ways to limit just how much current flows in the grids.
