This kind of comment is why every single project needs to be justified with "What problems are you solving?" and "What usecase are you supporting?". Because I could 150% imagine somebody getting excited about this and then:

1) Framing it as such with poor justification "a lot easier to manage"

2) "This would be a huge rewrite of some internals" Becoming a multi-year migration quagmire

3) The dawning realization that you have used a write-heavy architecture in a read-heavy system
