Suggestion: Please support DataTypes.UUID.BINARY

From the documentation

The CHAR and STRING types expose the BINARY property

I think this is also needed for UUID data type so we can store it as BINARy(16) is MySQL.

for example:

sequelize.define('model',` {
  uuid: {
    type: DataTypes.UUID.BINARY,
    defaultValue: DataTypes.UUIDV4,
    primaryKey: true
  }
})

I could not find any way to map a UUID field to BINARY(16) on MySQL. DataTypes.UUID and DataType.STRING.BINARY give ER_DATA_TOO_LONG error code.

Start by locating the UUID data type implementation and the MySQL dialect handling for binary types. Reproduce the reported ER_DATA_TOO_LONG error with the example model, then trace how UUID and BINARY types are rendered. Done means UUID.BINARY is supported for MySQL as BINARY(16), with coverage for the resulting definition.
