Description
Looking at the changes in #15230, the fact that = produces valid code (as argued in #15115) seems to be a point against using it. Many sentences appear to use constructs like:
Use :rc:`something` to do something.
or
You can do something by setting :rc:`something`.
These will become:
Use rcParams[something] = "default" to do something.
or
You can do something by setting rcParams[something] = "default".
This implies that you should set the rcParam to its default value, but those sentence often just mean set it to anything.
