Fair enough. Dithering would still be an option though. But if it's not done I agree there can be visible stripes in some cases.
Also I wanted to apologize for the negative wording in my above comment. That was uncalled for, even if I think HDR is totally not worth it at the moment.
Yes, but how are you gonna accept pull requests? You need a frontend and a frontend needs an account.
Of course, all of these alternative forges (gitea, forgejo, gitlab) can be self hosted on your own private server.
