Financial Backer for fix/feature

Hello,
I read on some issue that some dotnet main project may be understaff.
And i was wandering why for this project there isn’t a system to pay for a fix/feature like reactiveUI with open-collective-bot ?
The OpenCollective of the dotnet foundation seems a litle forgotten. It’s not even mention on the website or Github. What the point of view of the dotnet foundation about financial support for issue? The same as ImageSharp?

I also remember a dotnet standup where how much person each team where compose. Is it still possible to know now ?

Thanks,
