libxl has been made to "make common the low level operations of actuals 
toolstacks", so that every toolstacks will share the same code base to 
avoid code duplication and also give user more flexibility to move 
between toolstacks.
Any others goals you have in mind, is a part of your own goals, not 
libxl's. Whilst i'm happy to see more assumptions removed to have even 
more generic code, adding assumptions on the other-hand, related to name 
in this case, is a non-starter.
