There is more, e.g.:

- You cannot interpolate an expression sequence, it will cause the 
format string to get out of synch with the arguments.

- DIP1027's format strings allow manual overrides that may then be 
incompatible with the library functions.

- DIP1027's format strings require the user to manually escape e.g. '%s' 
so that the library does not mistake it for a format specifier, even 
though the user does not otherwise interact with format specifiers at all.
