Chiming in here to add that I'd appreciate the ability to render 'standalone' (i.e. no '=') query-string keys in order to distinguish between absence-of-value and empty-string situations.
The backwards-compatibility concerns in here are genuine, so perhaps this could be introduced as an argument to urlencode with a disabled default value, allowing developers to opt-in.
>> Unless someone can point to a "real" web server that does something different with "&foo" than with "&foo=", there is no reason to make a change to Python.
There's a popular nodejs library that makes this serialization distinction explicit: https://github.com/sindresorhus/query-string#falsy-values
I've developed a Python 3.7-based set of commits[1] to address this issue. I haven't yet opened this as a pull request since I see that Python 3.7 is in maintenance/bugfix mode[2].
In case a new urlencode flag would fall under the category of feature, I'll aim to develop a subsequent set of commits against the master development branch soon.
