Crusader Kings II hasn't been updated since 2021, and it's fair to say that it's been put out to pasture in favour of the sequel at this point. Mods like CleanSlate have accumulated a substantial amount of fixes for bugs and inefficient scripting which haven't made their way into the official release and likely never will, but the rules say you have to choose between taking advantage of those bugfixes and earning achievements. (CleanSlate doesn't even include fixes for historical inaccuracies—CK3 got an update to address the fact Murchad mac Donnchada should never have been listed as king of Munster, to give one example of many, but CK2 is still incorrect despite it being much simpler to fix since he's not tied to a tutorial.) A patch to let people gain achievements while playing an overhaul mod like CK2Plus, HIP or Tianxia would be very appreciated, since the incentive to play pure vanilla CK2 diminishes the shorter the list of things it offers that CK3 doesn't becomes.
 
While I personally don't have a problem with this, and I'm aware of other games which allow achievements to be earned using mods, I very much doubt this will ever happen.

First, I suspect it's possible to write a very simple mod which would instantly grant every achievement. (Set all of the character flags, run the game for a few days, bingo bongo achievements unlocked-o.) And, even if it isn't possible, it'd be easy enough to write an instant unlock script for any individual achievement. (Eg: "Grant every title to the player character" would work for quite a few achievements, across multiple restarts.)

I personally don't think "cheapening the process" is a particularly good argument, but many people think that it is. And it'd be a LOT easier (and less legally dubious) to download a mod to get an achievement than to use a Steam achievement unlocker.

More persuasively: AFAIK every Paradox game uses the checksum system for achievements - if you don't have the requisite patch+checksum combo then you can't earn achievements. IE: It seems that Paradox has adopted a philosophy across all of their games that "mods disable achievements". And I doubt they'll change that policy for CK2. Especially as that would require some amount of work, and they currently seem to be unwilling to do anything noncritical for CK2.

That's no longer the case. CIting from CK3's wiki:

Since version 1.9, neither Ironman mode nor an unmodified checksum are required for achievements to remain enabled.
