I talked to them about this before, it's really to control data storage. Maintaining all past leagues would take up a lot of space and also degrade database performance.
I'd argue that the growth and performance gains in storage over the last two decades means they could lengthen the retention rate on these leagues, but that is probably a low level backlog item for them.
Best thing you can do is maintain your own data for leagues you care about.
