I noticed that weight does change some inn dialogue, which makes me wonder if there is any features planned for it. Cause while no visible changes occur, it feels like there at least is or was a plan for weight based stuff.

Yeah, you're definitely picking up on something there.

The weight system is still very early in development, but I do have plans to make it more than just a number that affects a few dialogue lines.  

Eventually, I want Ryara's appearance and some interactions to reflect her weight progression, including some small CGs/illustrations for her chubbier stages. Nothing too crazy, and definitely not something that's fully implemented yet — I'm still figuring out how I want to integrate it naturally with the rest of the systems.

will there be bbw and ssbbw for ryara maybe related to milk like a feeding tube whie she is being milked
