I 100% understand what you're talking about. The sense I get from looking at the forums is that no one is working on any "popular" games, like something you would see on Steam with more mature themes. I get a feeling most people use Construct purely just to mess around, or to make arcade-y mobile games. I'm not saying that's all there ever is, or that's even a bad thing, but that's 90% of what I see.
I'd personally like to more games made in currently trending genres (2020) that release on Steam. Like rogue-likes (Dead Cells, Hades, etc.) or base building / economy sim / survival games (Factorio, RimWorld, etc.). But those are massive projects that take a lot of time and skill to complete so I understand why Construct users don't make them. But I'm just hoping someday in the near future to see at least one person launch a financially successful game on Steam.
