[development] type(N) in MySQL numeric type defs in core schema

I'm going through the core database code (as part of my role as
PostgreSQL maintainer) and have stumbled upon an interesting tidbit.
The use of (N) declarations for integer types in CREATE TABLE statements
is useless. From the MySQL manual:
"Another extension is supported by MySQL for optionally specifying the
display width of an integer value in parentheses following the base
keyword for the type (for example, INT(4)). This optional display width
specification is used to left-pad the display of values having a width
less than the width specified for the column.
The display width does not constrain the range of values that can be
stored in the column, nor the number of digits that are displayed for
values having a width exceeding that specified for the column."
Given that, why on earth are we even using them? I propose to strip the
(N) declaration from core schema files. It'll provide a much quicker
path between MySQL and PostgreSQL declarations.
Any complaints about this proposition?
