But I think the UHF connector is just not that "bad". So, manufacturers will be unwilling to change to something else that is just not clearly superior in most ways. I think the TNC connector is the way to go, at least on LMR equipment. But at frequencies below 450MHz or so, there just isn't a real clear advantage, when all things are considered. In my experience, I have had more problems with mechanical problems with mini-UHF connectors (percentage wise) than their big brothers. I just don't see anyone gaining a huge advantage, or even a small one, by switching connectors used on equipment that operates at VHF or lower frequencies. Probably equivalent to shortening the feedline by 5 inches, just won't be seen.
