As Wilhelm said
At the very least, it keeps a core of fixed wing naval competency alive.
To start these core competencies from scratch all over again once it is lost is a very long and expensive business.
This is the primary reason Kuznetsov is kept.
It also allows them to develop or discard features and doctrines in a potential follow up carrier.
Even if they started building now, the entry into service of a potential new Russian carrier would not enter into service before 10 years.
In the meanwhile, even with the use of the NITKA training center near Saki in Crimea (there is another one, in construction in Yeysk in Krasnodar Krai, but apparently the construction has stopped) you could only simulate carrier takeoff and landings but not carrier operation altogether.
Even if only as training carrier, the Russian Navy will have to keep the Kuznetov in order to be to maintain a carrier based aviation and keep trained and current naval aviators.
At least the transition from operation from the Kuznetsov to the new carrier should be easier than starting again with only ground based carrier simulator experience.
