<pre>application/gdalvrt+xml would just mean what the organization that defines the format is. People could reimplement that from scratch
Note that there is potentially the OGR VRT format (that could go as application/ogrvrt+xml), but that is a separate schema and likely less used than its raster counterpart.

<div>It's possible that ArcGIS has independently implemented
VRT, but I think it's more likely that it delegates to GDAL. I
think it would be possible to craft a VRT doc that would
reveal some details -- such as one that uses GDAL's embedded
Python pixel functions to dump some system information -- but
I don't have access to ArcGIS to try it.</div>

Do you count ArcMap or ArcGIS Pro as self standing software
or rather as<br>
applications that use GDAL? They read VRTs pretty well but
for writing some<br>
developer tools are required<br>
