Indeed, but... protocol drivers don't have probes, do they? There is a distinction between "formats" and "protocols", and only formats need to be probed for. > A minimal configuration excluding all of these drivers takes > around 3 ms to reach main(), and each of these drivers respectively add > times of approximately 0.2, 0.9, 1.2, 2.5, and a massive time of 41.6 ms > to the time to main.

All this I entirely agree with. Paolo
