Hi Mark,
Ok, wow! What an extensive and detailed post! Great work and thanks for sharing!
I agree that it is best to have this fixed/adjusted in the product. Have you done a feature request for this? --> https://www.vmware.com/company/contact/contactus.html?department=prod_request
Thanks again!
Yeah i could do that 
,
I think it's a known issue and that for now there wasn't much of a solution.
I'll take a look at the page you linked to see I can fill in a feature request, maybe they can also find a way based on event handling from a DEM agent or something. since that service is used a lot in Horizon environments anyway and runs. or maybe even the horizon agent itself.
