Interesting, I didn't know that.

A real-life reason created something that is actually kinda cool in-universe.

Voyager had some FPS games (Elite Force iirc) that were fairly standard Quake-Engine early naughties shooters with a Delta Quadrant Flare that were okay, but actually had a clever inventory system.

The way they explained how you could cary a phaser, a compression phase rifle, a special "infinity modulator" for fighting Borg, an an over-the-shoulder mini torpedo launcher, and more was that you had a mobile transporter buffer that held all your equipment, and the weapons would beam into and out of your hands as you changed weapons.

The point was they are supposed to be beyond the need for pockets. You were able to just stick anything you needed to carry with you anywhere on your clothes. OG Trek used velcro and prayers to pull off the effect. Later shows just kind of shot around it.
