Thanks for attempted answer, Barberlives123. You ignore one important fact. The icon appears to be purposed.
When any Docked app uninstalls itself, it removes its Dock icon. For the Apple-friendly app that is Docked, moving that friendly app to the Trash also removes the Dock icon.
Remote advisor adds a special twist to that simple Dock icon dance. When the Remote Advisor is removed it may or may not appear in Trash: that is it may remove itself permanently, or not. Trash presence for rare Engineering involvement can permit re-uses of Remote Advisor by removing it from Trash (extremely rare reactivation of tagged Remote advisor session). Trash or not, when remote advisor closes its descriptive Dock icon changes to a Dock semitransparent question mark that is useless, in the present support environment. Perhaps an intended reminder. Additionally, the question marks disappear eventually. Perhaps indicating an Apple Team resolution?
Descriptive active icon or inactive question mark, there's a lot happening under the surface of that adaptive Remote Advisor icon. I just wish that active or inactive, that icon would open a customer version of case in a specific, permanent URL collection. Specific to each Apple customer's Apple ID. I paid $2.79 for a permanent storage space of 20TB, 5 years ago (sitting there un-used). There's plenty of cheap resource that Apple can use to host permanent Remote Advisor collections, one permanent collection for each Apple ID. See a Dock question mark? CLICK! Open your Remote Advisor collection, naturally with your most recent case number highlighted and ready to open with another click on your Apple ID page's Remote Advisor collection.
Associated personnel and interface management would be a very minor corporate logistic. Apple Support currently runs a very sleepy under-deployed case-online system. Market that and grow it. A unique and as yet ignored Apple Market capacity.
