Do you need brakes on a trainer / on rollers?

No. For fixed trainer, it should be obvious. For rollers, rolling resistance is higher on rollers than on flat surface. Wheels don't also have much momentum, so you can slow down by freewheeling for ...

Do you need brakes on a trainer / on rollers?

I find brakes help with stability on rollers. When mounting/dismounting hold the brakes so your bike does not roll off the front or back of the rollers. Additionally, if you lose focus while spinning ...

Wahoo Kickr Snap vs Kickr Core: both good for at home training? Is the Snap suitable for hard workouts?

If possible, it is better to get a direct drive trainer like the Kickr Core. They have better road feel than wheel-on trainers like the Kickr Snap. Additionally, with wheel-on trainers, you can get a ...

Are dropout adjustment screws necessary on an indoor trainer?

Your intuition is correct. The screws aren't strictly necessary on or off the trainer. The clamping force of the quick-release skewer should be enough to secure the trainer or wheel to the frame.
