I disagree. This surely depends on the type of crud application you're trying to build. We have a few in house business apps here, REST API and a JS frontend in the browser. Works fine, and since all our operations are atomic everything that doesn't come back with a 200 OK is fairly easy and generic to handle. The system also wouldn't be really usefull if the data weren't always up to date. I get the point OP is trying to make but it really depends on what you are trying to build.
