Huge risk, and it's either a hit or miss.
Huge risk with who though? The overly vocal message board crowd who tend to make the most distaste noise over such shifts in development typically aren't actually the ones ever pushing any financial needles.
The greater surrounding risk reality here and as we've seen in pretty much every advanced content success game like this one is seeing it's support level plateau off instead continually expanding and drawing in new interest. Which will always typically happen after all the girls in the game are fucked/conquered, and once those new first time players checking in on the latest update are not ending that playthrough still chasing what's overwhelming the most effective carrot every single game ever has essentially built the lion share of their great financial base on - "Great game and can't wait to fuck that girl. Here is support money to better push the progress along".
The belief that games need and tidy "endings" to make money, or ever do so by catering to the guy with 5000+ posts here continually hyper analyzing their pixel relationship with any one of a game's girls, is the stuff of pure f95 created fantasy. For a developer like Icenton with top tier production value going into his games, fresh/new content releases will always be the bigger and safer financial "hits" after reaching a certain point it's a game's development then continuous rehashes of already pre existing sexual encounter content. That's just the way it is whether people here like it or not.
The interest will be there in mass. No doubt.
