The little tab engages the helicoil insertion tool. It's not a retention device.
The helicoil is held in by the external threads, unless you epoxy it in. Maybe Loctite would work too; I've never used it on a helicoil.
Edit: Whoops, missed 2many's response. Sorry for the repeat.

This has been very educational. I'm tempted to buy some Eldi bushings and practice rethreading old crank arms

Helicoil = hardend steel wire ground @ 30 degree incuded angle & wound to form a thread. Eldi is a solid insert, threaded on the O.D & I.D. I believe the helicoil to be the better of the two options. Either way be sure to get it square. Slightly canted installation will be very noticable.
