I don't know. I'm still sort of speechless (in my mind's eye) over how simple it was for Putin to insert a whole layer of loyalists above regional governors to approve whatever he had in mind... despite objections from the parliament and carefully phrased cautionary remarks from some of those governors.
Russia is not a country that I would ever have regarded as an example, or model, to look to for systems of government, especially anything to do with democratic or accountable government, or a genuine separation of powers or a law based state.
This is nothing to do with Putin, or Stalin, or Lenin, or the Tsars; it is the country's history, political culture and default traditions. Twenty years of reform (especially economic and political reforms reforms which failed to deliver on utopia, and crashed the economy and destroyed living standards) was hardly going to undo the memories, habits, sense of security and political traditions of a thousand years of autocracy, and autocratic and authoritarian government.
So, Putin, in essence, was simply tapping into older - and very familiar - traditions, re-branding them as authentically Russian, and doing so successfully.
More to the point, the test for him - and why he is still successful, and something most western commentators miss - is that the west is not the point of comparison for Russia (not since the reforms of the 80s and 90s are thought - somewhat unfairly - to have crashed the economy and destabilised the state), not culturally, not socially, not economically, and certainly not politically. Rather, the comparative test is that of 1,000 years of Russian history.
If Putin can show - and he has shown - that he can deliver a degree of security and stability, half decent living standards, the right to travel (for study, work, leisure), live abroad, study abroad, and work abroad without penalty, and to earn money abroad (and return home with it), earn money at home, (and keep it) , a half decent health system, not murder his citizens by the million (a few handfuls hardly count in a country with such a history), not get involved in catastrophic wars, by the standards of one thousand years of Russian history, he would be classed as a pretty good leader, because that is a far better deal for Russians than what they had received from almost any of their other leaders over the course of the past thousand years of their history.
So, dismantling the limited powers of a parliament the was hardly out of its political short trousers, and stripping the governors of an independent power base hardly counts in the wider historical and political context.
