I think it's unique to trail bikes, that where I ride that stupid thing manages to see non-trivial impacts at least once a month, but none of them are of the frame-shattering variety.
I think there is some engineering validity to loading up a couple of threaded inserts that are reinforced to be partially load bearing rather than having a big shear load dumped into the strongest part of the frame via the crankset, but I think either answer practically outlives the cost/headache of replacing chainrings.
For repeated minor hits, I think either one works, and since I wanted a guide primarily and to minimize weight overall with that happening, I still feel like this is the optimal answer for the cost, but finding stuff on sale always plays a role in that.
