Well they are being somewhat dogmatic, personally find it hard to gain active counterplay against it. In the 4Nf3 line, which think is perfectly good, play can play 4...Nf6 5e5 Nd7 transposing to the Korchnoi gambit. Black has some possibilties based on knight being on f3. Black can also play 4...c5xd4 5Nxd4 Nc6 which is a sicilian type, or sometimes direct transposition to Paulsen sicilian. So for me 4pxp is more of a problem because black's position after 4...pxp or 4...Qxp are kind of dull, some of the positions black can hope to reach are more drawish than equal.
Very interesting observation 2move. Yeah I was wondering myself why they released the tension. I suppose 4...exd5 does limit some of blacks options.
Yeah very interesting for sure.
