Or more marketing than anything else!
I think photographers seldom shoot at 1:1 magnification. More often they need macro lenses for 1:8 - 1:2 shots. But it's nice to know that my lens performs fine even closer than I need.
I have a Makro-Symmar optimized for 1:3, and this is its quality at 1:1:

Tip-for-tat by simple.joy, on FlickrYou certainly won't hear me complain about that... 😉 It's also more than fine at infinity when stopped down a bit, according to Rob de Loe. Sure it won't reach the sharpness of the best lenses optimized for landscape work, but I doubt the difference will be dramatic.
Nothing to complain about your pictures.😅 They are fine.
But I complain about Rob's claim. I checked this with my Apo-Digitar-M a couple of years ago. Almost at infinity, focused to ~ half a kilometer, the image circle, or with Rob's term, the circle of good image quality was not even covering the FF frame. I have better lenses to landscapes. But not better ones to shots at near to life size!😏
Symmar-S 135mm is quite good a lens to close-up work too. Here around 1:3 at f/8.
