I don't know if it has come up before. I think what you are proposing is fine, but for a different reason than the one you are suggesting. Even assuming for the sake of argument that the IRS' position is correct, this is not a "forfeiture." A forfeiture results from an allocation required under the terms of the plan which was subject to a vesting condition, i.e., a risk of forfeiture. While we call these corrections of impermissible allocations "forfeitures," they are not forfeitures.
