I would think that there would be a place in the market for:
1. Lightweight approach shoes. (Nope, Evolv Cruzer would have been close to lightweight if they had used something less daft than canvas for the uppers, but they have now been discontinued. The lightest approach shoes on the market now are about the same weight as two camalot 5s. No one clips that to the harness unless they must. The lightest trail-running shoes on the market weight about as much as a quickdraw, for comparison)
Back to this - that's precisely what I want! I've got Saucony trail shoes, which grip well on both wet/dry rock and typical Scottish heather, grass, mud etc. But, they are sieves, so let any hint of water straight in, don't quite have the stiffness and burliness required to last more than a season, and no clip loops.
I've just shelled out on Scarpa Crux's, which are great, but too heavy and the sole is not lugged enough for my liking. For the amount of "actual" scrambling I do, a "climbing" sole is just not good enough.
Was looking at the La Sportiva Guide TX: https://www.sportiva.com/tx-guide.html
but would like to try them on, and they're not an awful lot lighter than the TX4/Scarpa Crux anyway... Maybe the Jackal? https://www.sportiva.com/jackal.html
