This spectrum was clearly going to go to 5G at some point, and I don't care all that much how it got there, but with even more spectrum allocated to 5G, I confidently predict that mobiles will be even more fragmented than before. Even now, there are at least twenty LTE bands in common use. However, each operator usually only has one or two main bands that are available everywhere, and hence a device must support one of those in order to be any use on that provider. Manufacturers don't seem to be all that interested in covering those comprehensively, instead making their devices with an assortment of a few bands selected at random and, if necessary, making six different versions that are tailored to the frequencies used by one particular provider. The result of this is that it is hard to move devices on to or off of a provider whose band isn't one of the most typical in use. With 5G having spectrum that was previously not available to mobiles at all, that means a lot more bands, and even more effective constraint on which devices work with a provider.
