At this point in time(over 30k UMC's out there), there isn't really much Tesla could do but supply band-aids for the UMC, which they are doing. The biggest flaw with the latest UMC's are the tiny power carrying pins that the adapters attach to. They work as long as you keep the adapter flush, but overheat when there is a gap.
A simple adapter/UMC redesign that involved a thread-on connection of the adapters to the UMC would have solved the majority of their issues, but now that would involve handing out 30+k free UMC's, which I'm sure that Tesla wants to avoid, hence the band-aids. This is a classic case of when cheap becomes very expensive.
