The view Inventory/Hosts is also showing disabled hosts. It's not apparent there, whether a host is disabled or not. Furthermore, that seems inconsistent: For instance, you can't look at graphs of disabled hosts. Why would you see the inventory then?
Personally, I'd sometimes like to look at historic data from a host that's now disabled.
I'd suggest to either hide disabled hosts away or make the link red, like on the search result page.
