Please add the ability to publish group layers in either a feature service or hosted feature service. Currently when I try to publish feature classes from ArcGIS Pro that are organized into group layers I get a warning that the group layers will be ignored. My coworkers or I then have to manually group the layers back together in any web maps that use that feature service.
I prefer publishing data fully configured (symbology, popups, visibility, etc.) so that others can just add the data and use it immediately. Organizing the data with group layers makes interacting with the data much easier when many layers are involved.
