My interpretation is, Making modding easier is because they are designating Assets as actual mods, when they aren't mods. They call it an "Asset Mod".
Real mods actually modify game code. Mod is short for modify after all. I don't see making it simpler, but maybe making a more advanced mod tool, so mods can work together more cohesively. This means less downtime on patches and diagnosing conflicting mods easier. I assume it's more Harmony based type thing. Harmony sure made mods work better these last few years of CS1.
Also, Skyve mod was posting as for CS1 and CS2, so maybe Skyve will be merged with Harmony to really get modding going smoothly in CS2. And hopefully working in CS1 as well, with Paradox Mods too. Then we can finally get rid of the proprietary Steam Workshop and have trouble workshop.
But don't be fooled. You will not get any real modding for consoles or MS games. They can't let mods in, or people will kill the console interface. this would be a nightmare of epic proportions if allowed. Best case scenario, is devs could authorize certain mods to the base game, but then they wouldn't be actual mods anymore as they will be part of the game. But it could allow income for modder through the devs, like they do with Content Creator Packs (CCPs) of CS1.
