This is required when we need to match MySQL behavior for data that requires column type information as well. For example, the binlog event metadata makes no distinction between events for a BINARY(4) column and events for a CHAR(4) column with a binary collation like utf8mb4_bin. So we need to know the underlying MySQL column type in order to handle them disctinctly -- MySQL pads (fixed length) binary columns on the right side with null bytes, but it does NOT do that for (fixed lengthed) CHARo columns, regardless of the collation.
