Wouldn’t the global web.xml provide sort of the same solution - if it‘s really Sumit‘s intention to provide a custom 404 page only, for all apps? The Root-context approach may not work, if you hit a bad request/400, right? > 2.

It‘s not available in 8.5 though, that‘s why I used a CustomErrorReportValve until now. good to now, that will indeed remove complexity, as I‘d always have to deploy a global lib.
