It's not like it's only one guy working on the game and the pre-tech updates didn't really affect the tech-side much, given that they were basically just scenes.
These updates are essentially meant to add a bit of content that people wanted, while the tech update is being made. I mean, having too few scenes has always been and will always be a major weakness of the game, so every additional sex scene is objectively totally welcome.
Then again, it does again take way longer than it should, especially because the backgrounds are indeed done for a few weeks by now and there's isn't that much of an excuse to be this slow on the technical side. Not that it'll change much overall, but it looks bad - again.
