Sponsors maybe? Adding features because somebody influential wants them to be there. Either for money (like shovelware) or soft power (strengthening ongoing business partnerships)

I love DeArrow so much. Best addon I’ve ever donated to, very worth it

It’s largely incidental.

Soft-tissue cosmetic surgery doesn’t last. They’re foreign objects in the body, so over time your body tries to break them down. Lip filler slowly diffuses around the bottom of your face, for example. Botox paralysing muscles affects strength and elasticity.

So it’s a cursed treadmill. You can’t stop getting surgery once you start. A single surgery will look worse than your unaltered face if you only have one, so every few years you have to get it again.

But… all the old stuff is still in there. The muscle damage accumulates. The filler accumulates, and is impossible to remove. You might remove some of your own tissue to ‘reshape’ as it gets more advanced, but many just ‘top up’.

Either way, you are permanently altered. They don’t choose to look like this, they choose to make minor adjustments to look younger/hotter/etc that slowly turn them into this.
