I don't think this needs to be an all-or-nothing thing, and aside from a few items, it seems pretty standard. We start off with the Zero to Prod model, and when handlers become too large, move them over to "Repository" types. GET usually stays in the handler, vs POSTing a new request for an action that may include several DB calls, channels, async tasks etc.. goes into a "Service" type crate. Its usually little work though. As far as separating "entities" from requests/responses, that seems to be the norm in any language/framework. You don't want secrets to be responded when you create something, or all of your internal properties. When there starts to be too many config knobs, things are extracted to their respective places. I like that this lays out out a framework for it. It doesn't necessarily mean I would start there.
