Would you be opposed to SE implementing a program to scan for addons/parsers?

The level of invasiveness they'd need to have anything worthwhile means I'd just stop playing immediately.

I've never played Valorant or a few other games for similar reasons. Besides, it'd be a bit of a slap in the face for SE to implement some kind of client-side detection instead of use that development time to actually make the game better. Especially for a dev team that consistently claims things are impossible until they're shamed into implementing it by third party stuff that proves it's actually possible.
