Black continued 4...d4!?, with Andrew Ledger commenting in Chess that "White will get decent dynamic chances, given that he has the extra move and Black is committed to ...e6."
In my post I pointed out that 4...d4!? is the top choice of Stockfish18 and Dragon1, whereas the engines reckon the most popular continuation, 4...Be7, allows White to gain a slight edge with 5.d4 or 5.0-0.
So the question arises as to the soundness of ...d4, and I think it will be interesting to investigate this.
Note that a purer Réti move-order to reach the diagram would be 1.Nf3 d5 2.c4 e6 3.g3 Nf6 4.Bg2.
In that sequence, Black has the option of 2...d4!?, which, while playing through Bazakutsa-Hobson, I seemed to remember used to be frowned on in old opening books.
My memory was not faulty, eg Reuben Fine in The Ideas Behind The Chess Openings claims pushing ...d4 on move two "is somewhat dubious," because it is "uncertain whether Black can maintain his powerful wedge at d4 under favourable circumstances."
However, Fine adds that "it is essential for White to hammer at the Black d pawn early, or secure compensation in some other way."
He reckons both e3 and b4 are necessary, and argues that 3.e3 is the best continuation.
A more modern, and more specialist, book, Easy Guide To The Réti Opening, sees Angus Dunnington recommend 3.b4.
He admits "theoretically Black should be OK," but argues that the complicated lines arising will not be easy for Black to handle psychologically.
However, it is again interesting to note that after 1.Nf3 d5 2.c4, the engines agree 2...d4!? is Black's best continuation.
The possibility of 3.b4 has persuaded some players to delay ...d4 in favour of 2...e6, when 3.g3 continues the "purer Réti move-order" mentioned above.

Here Stockfish18 changes tack by recommending 3...dxc4!?, narrowly ahead of what is overwhlemingly the most popular continuation, 3...Nf6. Dragon1 also comes to prefer 3...dxc4!?, but by a tiny margin over 3...d4!?
After the commonest move, 3...Nf6, White usually plays 4.Bg2, reaching the position in the first diagram, where, as we know, the engines like 4...d4!?, albeit with 4...dxc4 close behind, and with some fluctuation in the evaluations.

The bottom line seems to be that ...d4 is certainly playable, and may even be best, at moves two, three and four.
However, be warned that after 4...Be7 5.0-0, reaching a position occurring 27,651 times in Mega26, ...d4 loses some of its charm, at least for Stockfish18, which reckons both 6.e3 and 6.b4!? are promising for White.
And be especially warned that 6.b4!?, apart from facilitating Bb2, sets a trap, which has been fallen into by a 2206, namely 6...Bxb4? 7.Qa4+ Nc6 8.Ne5, when best seems to be 8...Rb8.
At first glance Black looks fine, but Gulruhbegim Tokhirjonova (2350) - Rui Yang Yan (2206), US Women's Championship (St Louis) 2023, continued 9.c5!, when Black's best may be 9...0-0!? (the game saw 9...Nd7?!) 10.Nd3! Ba5 11.Bxc6 bxc6 12.Qa5 e5!?, but Black does not have enough compensation for being a piece down.
