Adding volume spacers will make the final part of the suspension stroke firmer, requiring more force to bottom out.

For a more progressive spring rate you need to add volume spacers (or remove if you are not using enough travel).

As for whether or not it is an issue, this is my first FS bike, so I am not really sure how a hard bottom out would feel. Forks and shocks are expensive, potentially complicated, sometimes confusing, and easy to get wrong.

Travel is simply the maximum distance that either the front or rear suspension of the Mountain Bike can compress, when absorbing force, before bottoming out.

Harsh bottom out launching you OTB on a 1 inch root - no bueno. The tire does rub the cable guide at times. The o ring never comes off. The lower amount of travel the lower amount of force absorbed. Fork zazen is usually fork doing its thing, you doing your thing, and using the travel without harsh bucking or having to ride like boomin' granny to stay on the bike. An older mountain bike may have an 80mm fork, which is hard to find now. Bottoming out happens when you reach the end of your suspension travel. The higher the travel the more force the suspension can comfortably absorb. It’s easy to get discouraged by mountain bike suspension. Not sure how true that is, but bottoming out is not going to damage anything.
But if it's happening too much, your suspension is set up too soft, and if it never happens, your suspension is too stiff.

The amount of travel will change the handling characteristics of the bike.
