ConfigParser parses section lines containing square brackets like '[spam [eggs] spam]' up to the first instead of the last occurrence of ']' preventing roundtrips:
Potential fix: change the second line of SECTCRE from r'(?P<header>[^]]+)' to r'(?P<header>.+?)'.
If the parsing behaviour cannot be changed, the user should at least be warned about supplying data that breaks the roundtrip.

This is a duplicate of bpo-20923 (#65122), which was rejected. To argue against the rejection you probably need to provide evidence that this is something that is actually supported by other common ini parsers. And that evidence should be posted to bpo-20923.
