There is an entire post from the devs on why Bottles is packaged the way it is. [https://usebottles.com/posts/2022-06-07-an-open-letter/]. If you put yourself in the developers’ position, it’s actually understandable. Distributions ship Bottles package filled with issues or straight up borked, users turn their frustrations to the Bottles developers instead of package maintainers, devs get frustrated and bombarded with issues that they can’t fixed. A ton of time, effort and mental health is wasted. I think the wishes of devs should be respected, even though the software is open source and you CAN package it however you’d like.
If you have issue with Bottles, you don’t immediately go to the Wine bug tracker. If you have issue with packaged Bottles, you immediately go to the Bottles bug tracker. There is clearly a big difference.
