I am similar.
I have found the process to be rather overly complicated; though I do recognize some benefit in more granular control in certain areas. Between running different versions of wine and proton, I have been able to do everything I've needed to and wanted to do with far less steps and time invested into the setup. I haven't really thought about bottles again until now.
However, I do think that it is important to support projects like these anyway -- as gaming on Linux is one of the few consistent barriers for people switching over from windows or mac; just because it isn't my cup of tea or that I personally don't see the benefit of it doesn't mean that there isn't a whole community of people who prefer to use bottles and enjoy the fine control over runners and such. In a larger sense, I think supporting them would be supporting gaming on Linux as a whole.
Very true! But I think how said technology is presented and making it easier to use or more understandable to certain people goes a long way.
Sort of like public intellectuals and hardcore academics. Hardcore academics are the ones driving forward new innovations for a particular field of study or another. Public intellectuals make said field of study more accessible to the public by providing descriptions and explanations in various laymen terms.
In a similar way, bottles may make using wine or different wine versions easier for some; or maybe the process of creating and setting up a bottle clicks better and makes the most sense for them.
