Well, it's not like anyone's trying to get the USSR officially reconstituted. But there does seem to be a very deep undercurrent of respect about what the USSR stood for (as a form a "Greater Russia", in effect), independent of the CPSU's hegemony over it.

As exemplified by, for example, Putin's famous statement about its collapse being "the greatest geopolitical catastrophe of the century". And the widespread contempt for Gorbachev for having presided over it (or at least for having caved into under far too generous terms for Russia's geopolitical adversaries).
