I wonder whether to which extent the interpretation of words like moot
influences the quality of API designs. I always though argueing (with
the goal of agreement) was a good thing, but by now I come to think that
I might be too idealist.

I am not sure of the "loose coupling" argument in the context of
large-scale software development.
You put element names, variables names in your query strings. You might
rely on the schema of the data to process the query result.
Now the schema evolves, you have to change your queries - is it easier
to change (=>loosely coupled) if you have your queries in objects, or if
you have them in strings ?
