Questions about leaderboards for previous seasons

I was looking at the FAQ, and I stumbled upon this:

It is a thread for consoles, and it says the following:

"Both new and old* Weave progression will be recorded in the leaderboards and can be viewed by selecting the arrows surrounding ‘Weave Expeditions’.

Please note: Old Weave progression will no longer be recorded, only presented."

The way I understand it, consoles have a way to see leaderboard rankings from previous seasons? Will this become a thing on PC too? And will it include the rankings from season 1 and season 2?
