Hi Brian,
I think that specifying plated holes or any other plated features at the
edge of the board is rather safe. The tricky step comes in the final routing
step -  here you cannot go with your router bit straight near the plated
hole since it will most likely rip the plating off.

Regards,
Yehuda Weisz
