Sure, but this is not the main reason for the EoCV reduction, charging power reduction and the changes in thermal management.
Simplified you can consider a cell with a li-plated anode as overcharged at 4,2V! This state results in heat production inside the cell and further cathode and electrolyte degradation. The risk for a thermal runaway of a complete block of cells is then much higher than the risk from randomly occuring shorts by dendrites and may not be stopped by the cooling system neither the electrical and thermal propagation protection.
Li-plating results from the fact that Tesla was/is using inappropiate electrical and thermal charging parameters for the given cells.
Or in other words: If they'd applied the parameters they are using now, your batteries would be in better condition now, but on the other hand you'd never have enjoyed the range and/or the charging speed you did more than a year ago and maybe would have complained about high preheating losses.
Imho Tesla in general tends to overstating and designing above safe operation limits.
Thanks for your input, and for pointing out these issues LOOONG before this thread, or batterygate, or chargegate, and Tesla's manipulation of the cars, existed.
