UK Universities as Foci For Infection?

I know that this is getting a bit repetitive but there are now reports that the rate of Covid-19 infection, within UK universities, can be up to seven times that seen in their surrounding populations (https://www.theguardian.com/education/2020/oct/12/fears-grow-student-covid-infections-england-wales-will-spread-into-local-communities). It is, perhaps important to note that university staff and students are probably tested more frequently and rigorously than people in most local 'communities', perhaps inflating the figures. Having said that, it is not at all unreasonable to fear that universities may come to act as foci for transmission of the virus to the local populace in the 'second wave'. These effects could be even more wide-spread, when the students return home, to all corners of the UK and beyond, before Christmas. The sad thing is that all this is highly predictable (and was predicted). It was pointed out, for example, that much of the university-provided accommodation is too crowded for a safe containment of the disease. The people who run UK universities also cannot have been unaware of what happened, somewhat earlier (they go back in September), in the USA. Covid-19 infections there became rampant in many of their institutions. Again, I think that the return of the students needed more careful and coordinated planning. Universities should not have been left to plan it individually (financial pressures vary across different institutions). Perhaps they should have considered (I know it would be difficult and costly), restricting the numbers of students starting university this year? Students could have been more strongly warned that the 'student experience' would be very different from what is traditional (much less freedom to do things and with massed Zoomification of most teaching). The students could also have been required to sign undertakings to stick to local rules (although blaming the students for this debacle is wholly inappropriate).
