What do you count as flaws though? The only one I can really think of was the dying battery but I doubt that could ever happen on a ds/3ds. Unless you're just talking about something you personally dislike about the game, I see no reason for them to NOT make it.
Day/Night system, evolution in certain areas, hidden abilities (plus extra abilities), more attacks (and pokemon), physical/special split (that you mentioned), etc. I'm pretty sure you get the picture. With all these extra mechanics added to the game, I'm pretty sure it will be worth a play through at least. Plus, both remakes have gained extra places to go and things to do so I doubt they would just skip over it for this game, which means you would not be "playing the same game as the original". You're skipping over quite a bit that has been added.
