I think that many projects use DHF Proposals to nullify their own risk in their own projects, which is just wrong in my oppinion.
I think Keychain is the only one from your list that I would approve a big sum of money to, because at least from my POV that application is used by almost every Hivean I speak to, but others could probably cut 50% of the support.
Exactly what I'm thinking..
Even wrote some questions about this upcoming proposal but got some AI answers.

Hope this „no personal risk“ proposal are not funded, even though i like the idea.
