Hi Dirk,

The idea is that there could be different popup dimensions in the 
future, and the OP would know which popup to serve based on the query 
parameters, without having to wait for the document to load before the 
JS runs. For instance, currently we believe that 450x500 is the optimal 
size, but new form factors will probably evolve over time, so passing 
the dimensions can make the popup extension more future proof for future 
popup sizes.

It would be nice to NOT have to rev the extension if we later define a 
mobile popup, or if display technologies evolve such that 450x500 is too 
small.

I proposed combining the popup and the language preference extension 
into a single extension, but I got feedback indicating that it's 
preferable to have 2 separate extensions.

I personally don't have a preference, but I can see how RPs and OPs 
could consider popups and language preferences to be orthogonal.
