Allow feature services with joined hosted feature layer views to have the data schema updated without removing the view

[Philip_Ohlinger]

Currently, if you have a joined hosted feature layer view  setup for a feature layer, you cannot edit the data schema of the layer in ArcGIS Online. This means you cannot add or remove fields, or alter the domains for the features unless you remove the view. This is extremely cumbersome, as we are using the joined hosted feature layer views for many of our features, but also need to periodically make changes to the data schema.

Please allow joined hosted feature layer views to be used while also allowing changes to the data schema of the features. This would save us so much time not having to continually delete and recreate the views.

Thank you @EricaNova  that's great. The steps you have taken are really clearly laid out.  I'd like to try this on a proof of concept I have time. My main concern is that this could cause issues with sync enabled hosted feature services. If it can be done by  editing the JSON then I'm sure ESRI can build an 'update Joined view layer' UI 

The fact it can be done in the JSON should not be a substitute for a UI. Can someone from ESRI please give an update when we are going to have the ability to update the schema on source layers as stated that we would here (June 2023 ArcGIS online release) When will we see this on the road map?

if there is a technical explanation for not enabling this then please tell us why.
