I've opened ticket [1]#18116 to track this cleanup change.
This change would allow to close a handful of tickets about half-backed
compatibility with deprecated MySQL 4.x.
More specifically the commit would make Django trunk require MySQL
5.0.3 or newer. This will allow avoid a limitation on the length
(<= 255) of char fields imposed by older MySQL versions.
Opinions on the proposal and the respective patch are welcome.
