It's not really something to talk about all the time. I mean, maybe if someone felt like saying "this old lore is my favorite" or "I like this lore in particular" in some discussion thread randomly, it's not like there were on-going developments to talk about. Varus' lore need development, even most fans who liked the old lore admit that. But we never got any. And never will, because they completely changed it. It's just something to be enjoyed occasionally, or when you hear some of Varus' lines in-game, which I always thought were some of the most intense and cool lines despite only having a few short ones.
So people did care before, they just didn't have any reason to proclaim it all the time.
