Offering interesting options against the big systems Nimzo, KID, Grünfeld etc. is one thing, the other is putting all this together to a coherent repertoire with all those problems of transpositions! Especially if you don’t have the semi-waiting move 2Nf3
I took a look again at Kornev‘s „Practical White Repertoire with 1.d4 and 2.c4“ (3 volumes, ~1000pages, ChessStars 2013/14) and splitted the coverage into
~55% the big d4 systems (QGA, QGD, Slav, Semislav, Nimzo, Grünfeld, KID, ModernBenoni, Dutch with 1...f5 2.Nc3)
~33% other/minor d4 lines (Albin, Chigorin, Tarrasch, Wolga & various Benonis, Old Indian, Tango, Budapest, Various after 1.d4 e6 2.c4)
~12% things could happen after 1.e4 (mainly Pirc and Modern)
Counting slightly differently Kornev could have shortened his coverage ~25% if he had restricted his coverage to 1...d5/Nf6/f5/c5/e5 and had recommended 2.e4! „whenever possible“! (And please no BDG, Staunton or Gibbins-Weidenhagen!))
1.d4 e6 2.c4 (not ...d5/Nf6) is a big subject and 1.d4 d6 2.c4 e5 is certainly something many white players would like to avoid!?
So I’m curious what Moskalenko, Lakdawala and Sielecki have in mind against that ...
