Modules are not being kept up to date with best practices

Hello,

We're running a chrome performance test on our site and we're getting the message that deprectated methods are being used in the javascript.  

We've traced this back to:

WeltPixel/LayeredNavigation/view/frontend/web/js/product/list/toolbar.js:                    xhr.setRequestHeader('X-Requested-With', 'XMLHttpRequest');
WeltPixel/UserProfile/view/frontend/web/js/content-init.js:                      var xhr = new window.XMLHttpRequest();

We checked the latest versions of the module and see these are still here.

Is welt pixel updating things to keep in line with best practice?
