This is why I always recommend against any kind of friction fits.
Now, the forces are less extreme on the first stage of a transmission, but I still wouldn't do it in the middle of the season.

Ah.

The loads here aren't even comparable.

No slot obviously is more secure, but slots can be used for motor c-c adjustment without issue in FRC.

A nice trick is to angle the slot away from the direction of force (for belts/chain) as much as you can fit. This not only increases your tensioning resolution, but decreases the friction required to hold position.

For gears you actually want to aim at the other shaft, as the forces pushing the gears apart are the lowest of the forces generated in that interaction.
