PEP491 states that "generator" is the name of the software that produced 
the archive without specifying if it is the name of the frontend or the 
backend. However the example it gives is the name of a backend.

In your example above I would prefer a different value to be used in 
each case (to help debugging), ie. to use the name of the frontend 
(although it is confusing to include the version number of the backend). 
The disadvantage is that the backend (which writes the value) doesn't 
know the proper name of the frontend and doesn't know its version 
number.

On balance it would seem that the name of the backend should be used. 
However in this case that should be 'pyqtbuild' and its version number 
(sip-wheel is the name of a frontend).
