Gut feel says that you should avoid modifying the table. An alternative would be to add your column to a new table and link to the original table to maintain referential integrity, so the original table remains untouched.
Another, fairly typical approach would be to create a new table with the added column, swap it out with the old table and then add the data back to the new table. Not a great solution though.
MySQL gurus will likely disagree with me.
