Are we talking about WotC official material only? Or also including 5e-compatible third party publisher (3PP) content?
There really isn't that much WotC official content coming out to call it anywhere near a "constant barrage" so I'd assume you're lumping all 3PP content together as "5e". There's no way anyone can follow all the 3PP 5e content but having 5e-compatibility is still very attractive (required?) if you want any sort of reasonable sales on your product. I use a bunch of 3PP content but anything that isn't 5e-compatible is an instant pass for me, so I certainly wouldn't call the 5e label "noise", it's very much the opposite
