Sorry it took me this long to write back.
The interesting part comes when you have the same app TWICE, one for the default profile and one for the work profile. Case in point: Gmail. I use my personal email from Gmail and my employeer uses corporate Gmail. When I enter Gmail with my personal account I don't have the corporate profile as an option to switch too. Instead, I have a second Gmail icon which only lets me access my work account.
Here is the app drawer in Hyperion Launcher:

It shows the personal Gmail icon on a tab called "Todo" (Spanish for "All"). Then, when you switch to the tab "Laborales" ("Work") you'll see ANOTHER Gmail icon which takes me to my work account.

Likewise, when you want to add a shortcut to Gmail, you get both options: personal or work. And same thing happens with Widgets: I can add a Google Calendar widget for personal or work independently. And in LLX, it should permeate everywhere an ACTION can be assigned to (swipes, double taps, folders...).
In LLX, right now, this would be my app drawer:

Just a single icon for Gmail (personal); work is nowhere to be seen.
That's the support I'm talking about. I REALLY hope it's feasible. I miss LLX.
