Why Valorant doesn’t have Custom Servers/mods

Kinda want custom servers or ability to add workshop maps, etc. Imagine prop hunt, zombie mode, jailbreak, surf, aim maps, etc… Would be kinda fire no?

This is just speculation but I believe Valorant wasn't built with those things in mind. If you go back to release, you see them prioritize their anti-cheat and fast servers which we are seeing the repercussions of it now. To optimize the servers to be as fast as possible they cut corners which in turn made making the replay client much harder. For Custom servers and mods, I think
vanguard prevents them from opening things up.

they can't even implement replay system even after 5 years of the game running publicly.

because its very clearly a riot product and not a game put out for the community to fix with little to no control from the parent company

I think it has something to do with anti cheat and safety but I may be wrong. Regardless every game should have mods and workshop stuff
