I take it you mean that warning to be for your software in
combination with MySQL.

Most RDBMS seem to do little things differently. Software
should be aware of differences, at least if the differences are
in non-standard extensions to SQL.

This is simply not true, unless you're using the obsolete ISAM table
type. The only time the AUTO_INCREMENT is reset is when you empty
the table completely with a "DELETE FROM TABLE" without a WHERE.
At least this is what the manual says.
