> TOML also is a good example of "creating problems instead of solutions": They deliberately (!) broke compatibility to the INI format due to "I can't stand unquoted strings". Yeah, emotional feelings about CONFIG FILE FORMATS.

INI is hard to parse because without quotes the parser would not know whether it’s a “True” as a string or True as Boolean value. Formal parser that can be included into a program as a library and would reliably generate internal config representation (e.g., read config file into an object in application memory that will be used to modify the behaviour) is a good thing and TOML helps with that while INI does not.
