Hey, thanks for this funding request!
IMO The other funding requests makes less sense if this task is not handled first.
I do think, we can indeed start with the routing/objectpathmapping part, even without having the Framework fully decoupled from the persistence layer. I even do think, that this would make more sense to do first, because that way we already reduce the direct coupling, because routing then only depends on Caching package, so we have one less dependency path to deal with.
It would also be much easier to get a small funding granted first, that already goes in the right direction.
