How necessary is undermining? (Fingertip magnet)
After reading and watching various magnet implant guides, I'm noticing some disagreement on whether the skin needs to be undermined to create a pocket for the magnet. The local wiki says that "the lack of a proper pouch will inevitably lead to rejection" (quite a strong claim), and yet sources like chironex's video don't even mention it.
Most professional medical sources only suggest undermining for relieving tension on the wound closure, although those sources aren't considering a foreign body (like a magnet.)
