Right now there is only Negi up to some point from white perspective and Vidit. Maybe, Bologan will have something to say about it.
Negi (chapter 26) from white perspective on the transposing issue, discussing 8.Ne5:
Quote:In one of my early attempts in this line, I did not notice the difference between 7...e6 and 7...Nd7. It was an unforgettable lesson in the move orders, as after 8.h5 Bh7 9.Bd3 Bxd3 10.Qxd3 Nf6!
The book gives mistakenly 10...e6 here, because it used the game via transposition.
Negi goes on to give the arguments Eric also gave here:
Quote:Black went on to equalize without any problems in Negi - Zenklusen, Biel 2007. Compared with the main line, the fact that he has played ...Nf6 instead of ...Nd7 greatly simplifies Black's task. If Bd2 is played, he can hit the centre with a quick ...c5, while Bf4 may lead to an unwanted exchange after ...Bd6 (with or without a check on b4 to provoke c3).
Vidit in addition also mention another point Eric gave as well: The quick possibility of ...Qd5 because of no knight on d7 hinders it.

I understand your question better now. After 7...e6 8.h5 Bh7 9.Bd3 Bxd3 10.Qxd3 Nf6! (instead of 10...Nbd7, transposing to 7...Nbd7), Black already has a plus score according to my database. As mn said, there are lines where Black can play ...c5 quickly and post the knight to the more aggressive square c6, and the queen also benefits by having a clear view to the d5-square and d4-pawn, as well as x-raying White's queen on d3.
Specifically, on 11.Bf4 Bd6 already looks very simple and equal for Black, though 11...Qa5+ may be even stronger. And 11.Bd2 c5! already looks excellent for Black. For instance, 12.0-0-0 Nc6 13.Bc3 Qd5, etc.
That being said, after 11.Bd2 Vidit does not like the immediate 11...c5. He gives your line as being equal and continues it, but he does like 12.Ne4 better for White:
Quote:12.Ne4!? Nc6 13.Bc3, Black faces problems with the development of the f8 bishop
Wei Yi beat Wang Hao here in 2017.
Because of this Vidit gave originally 11...Be7 12.0-0-0 0-0 13.Ne4 N:e4 14.Qe4 Qd5, but Grandelius won two nice games in 2017 simply leaving the a2 pawn unprotected with 15.Qg4! One of his opponents btw was non other than ... Schandorff. So Vidit updated his own video in the accompanying files, suggesting 12...c5 instead, but with a bunch of alternative lines following on move 13 it is not very clear without additional help from the video (not availabe for this line) which line exactly he recommends.
As you can see, it is not at all simple - even in the lines that are supposed to be good for Black. And in the main lines Black has to play sometimes a pawn done which also might be theoretically tough once the surprise value of the line has gone. See my post below.
Right now it is a good over the board weapon I guess, but with very good prospects for the stronger player because of many possible deviations and the overall complex position.

2. In the Classical Variation with 7...e6, where does his analysis meet Negi's?
