You could have a few built in options (like for domain filtering and customisation) for the privacy people. Could even be community sourced so there's no onus on Kagi itself.
So for example there could be a built in "developers" preset that might make domains useful to coding higher ranked (and down rank or block things like stack overflow clones). Etc etc.
Basically this could allow a smaller amount of customisation with less ability to identify a specific user.
I also use Orion and I do like the idea someone else had of integrating an option for Kagi Privacy mode into the "incognito" tabs specifically as an option!
