Rear Shock Shaft Mounted Bump Stops

Just curious if anyone if running this setup as opposed to or with a standard style bump stop? I mean there has to be a reason you don't see anyone running them on Tacoma's and my research has come up pretty empty. I was hoping maybe it would help slow the shock down as it gets close to full compression and maybe eliminate the need for a bump on the axle.

 

I'm assuming it's because the shocks or their mounts aren't capable of carrying the bottom out loads that go with having a shaft mounted bump stop.

 

I had that thought to and obviously I don't want my shocks to be the bump stops. I've seen Jeep guys run these in the rear and I would assume they have similar weights to deal with; however they are usually linked in the rear and not on leaf springs.
