New submission from Hugo van Kemenade <hugovk+python at gmail.com>:
The LegacyInterpolation class of configparser has been deprecated in docs since 3.2, but without raising a DeprecationWarning.
The 3.2 HISTORY file says:
> - configparser: the SafeConfigParser class has been renamed to ConfigParser.
> The legacy ConfigParser class has been removed but its interpolation mechanism is still available as LegacyInterpolation.
Searching the top 5,000 PyPI sdists, there's very little (if any "real") use of LegacyInterpolation. Details: https://bugs.python.org/issue45173#msg409685
Other configparser deprecations were added in 3.2, but with DeprecationWarnings.
Let's add a DeprecationWarning for a couple of releases before removal.
