Two cents:
$.01 -> Yes, the appropriate thing would be to contact ANOVOS & let them know before they make 2000 of them.
$.01 -> Even if they don't move them, it's not a hard issue to re-do compared to other EI type changes. Thus, I don't think it is much to worry about. Also, if ANOVOS gets feedback that tons of people are moving it, they will probably change.
