ArcGIS Server 10.7.1: Why WGS 1984 Web Mercator (Auxiliary Sphere) is compulsory when publishing with cached image service?

 

I couldn’t figure out why WGS 1984 Web Mercator (Auxiliary Sphere) is compulsory when publishing with cached image service.

 

Is there any way to publish with cached image service but with same coordinate as mosaic?

Tutorial: Creating a cached image service—Documentation | Documentation for ArcGIS Enterprise 

Note:

If the source of your image service is a mosaic dataset, it is important that you use WGS 1984 Web Mercator (Auxiliary Sphere) as its coordinate system, which is the same coordinate system used by ArcGIS Online, Google Maps, and Bing Maps.

which later state

If you create a mosaic dataset in a different projection then the one you need to use for caching, you should create a referenced mosaic dataset from the mosaic dataset in the projection you need. This is because you can't change the projection of a mosaic dataset.
