The trend you suggested at the end of your post agrees very strongly with Seilers observations.
The trend is moving away from polarized to more threshold. In the 90s pretty much workout was 1500-8k pace for track runners. Then daniels started pimping out low volumes of threshold work(right at the edge for sellers) and guys like Ingrebstein dropped the intensity some more while cranking up the volume.
At the lower end (say MP is 5 min and easy run is 6-7) there is about of a trend to back off a bit more. My impression is in cycling it is a bit easier to do that comfortably hard ( say 60 mins at say 5:20 effort) the most runners just can't do.
Obviously we are getting pretty nuanced here but the point is polarized training isnt much any different than most running programs for the past 60 years(Lydiard had his 3/4 efforts in base phase). You still have to decide what you are doing in the 10-20% work. Deciding you want to do polarized training really doesn't narrow things down much.
