You're asking for added features to change how the game is meant to be experienced, and it simply was not in the vision for the game.
For example, let's look at Pac Man. When beating Pac Man, should the devs provide the player the ability to despawn ghosts, or make 100 ghosts, or make Pac Man invincible, or make all the dots into power pellets, or have fruit appear every second, or be provided a map editor to make their own maze? Because the game doesn't have these things, does that somehow mean the devs are looking over the player's shoulders telling them they're playing wrong or tying their hands?
Cheat codes can inadvertently burnout players by experiencing all the content really fast in a matter that wasn't intended. Even as end-game unlockable content, this can remove any need to replay a game, and replayability is a foundational pillar of EVERSPACE. Sometimes having a sandbox mode or unlockable can be a good thing, but not always. Skyrim obviously does benefit, mainly because one of its foundational pillars is to experience the game however you want. But not every game is a Skyrim.
Could this feature make EVERSPACE better? I strongly feel it wouldn't. The dev console is clunky, unintuitive, and (at times) difficult to use. The only reason it exists is for testing purposes. Putting this into the hands of players could hinder the vast majority of those misusing it, while a sliver of the minority would actually benefit. With such tremendous room for error, the effort of implementing this simply won't happen. Sorry!
