In .NET, updating a WCF service reference can generate huge changes in a dozen generated files, none of which are relevant to understanding what a pull request is really changing.
When creating a pull request, It would be nice to mark files in the pull request as "irrelevant" so they are hidden from reviewers by default.
The reviewer could unhide the changes, but usually seeing several KB of
xsd files changing is unhelpful.
With this feature, reviewers would be directed at the important files in the pull request and the boilerplate changes would be hidden.
