Actually, I did not know that. Interesting.

If a remake is substantially different than the original, then it's its own game, really. It would be like saying Oath in Felghana is Wanderers from Ys; these two games are very different from each other. They're really not "the same game". Can't comment on SD1 / Sword of Mana, but I'm going to guess Sword of Mana is pretty different, and as such I think it should have its own entries. Otherwise, we might as well start listing the original game's platform in the represented platforms field for soundtracks because the original game's music came from that platform (and if the music is substantially different as well, then that's just more reason to give everything its own entry, game included).

My thoughts, anyway.
