In terms of mechanics, absolutely. In terms of content, not so much. The UK is getting one change (a welcome one) in terms of timing of rearmament. However, the
first post after the dev diary contains something that would be even better for improving plausible alt-history. (credit to

Did Paradox not know about this? Did you guys know but think it too farfetched (which would be incredibly ironic)? Did you know but not implement it because you instead spent your time implementing Communist and Fascist UK? This is the kind of stuff I'm talking about. I'm happy to see it will at least be looked into but it's telling that, even though there have been threads about it, mods have implemented it, and it was a fairly notable event, it's only after someone brings it up in a dev diary
after we have this elaborate Communist and Fascist UK setup that it's even considered.
You also reference Kaiserreich, and I would encourage you to examine the
depth of the world there, which is a point
@Robosoldier1 made earlier. The KR devs go through great lengths to explain the world as it is, and why it is that way. The base game doesn't. There has been some improvement from release, but still one can't help but wonder if historical paths are more unpopular because it's just assumed that players understand what's happening, so the flavor and background just isn't there for those who aren't as well-versed in history. It takes more than a paragraph mousing over France's national spirits to understand what's happening in France. I'm not asking for dissertation-level analysis in-game, but maybe something explaining what the Maginot Line is for people who don't know, why France has so few military factories for a major nation, or who all these key individuals are and what their motivations may be. WWII knowledge is quite lacking among many people, and constructing a compelling world with a few informational and orienting events here and there beyond "The Hindenburg Blew Up" would go a long way towards immersion.
