One thing to keep in mind is that the Bc8 is still a problem piece; ...dxe4 doesn't solve this problem, although it probably makes it easier to solve.
I don't think it makes it easier because dxe4 opens the position and the white pieces become active while this B on c8 stands in the way of the R on a8 somehow.
I tried this setup with black some years ago and all I got was +=
The Rubinstein can feel +/= until White actually tries to do something. It has the virtue of solidity, even more than the "ordinary" French lines with e4-e5. I wouldn't let some +/= evaluations scare you off, necessarily, even if they're strong player evaluations rather than computer evaluations (which should be considered but not followed). You're playing Black, after all, and +/= isn't 1-0.
The reason I think the Bc8 is an easier problem in the Rubinstein is that after b7-b6 or a7-a6 and b7-b5, the bishop on b7 has an open diagonal, rather than still being very bad as it often is there in the "ordinary" French. Purely to illustrate, think of this as a plan for Black:
1. I will castle, placing my knights on f6 and d7 and my f8 Bishop on e7.
2. I will play c7-c5 and exchange pawns.
3. I will play b6 and Bb7.
4a. If there is a pawn on d4, I will exchange pieces and control the d5 square.
4b. If there is no pawn on d4, I will advance my e and f pawns to restrict White's pieces.
That's how the Rubinstein can play if White is passive (or just goes wrong somewhere). You can't do all of that in order if White is paying attention, and shouldn't get it all in at all. But you shouldn't think of the Rubinstein as prospectless; you can instead think of it, as I do, as a Sicilian Defense where Black played d7-d5 first, then c7-c5, rather than the other way around (almost like the comparison between a Leningrad Dutch (f7-f5 first) to the King's Indian (e7-e5 first).
Below the GM level, this variation has perfectly decent winning chances, based on the same basic concept as the Sicilian: Arguing that after exchanging c and d pawns for e and d pawns, Black has a positional edge.
