The Picomix version of Stranded Isle will be going on its own leaderboard, alongside the Picomix versions of other games. This was inevitable, as the game changed so significantly. (There's a few bug fixes, a change to zombie behavior, widescreen, removed load times, etc.) It could never be with the other versions of SI that (mostly) kept things even.
And no, there are no plans to put the Picomix version within its own subcategory on regular SI leaderboards. We don't have version-specific leaderboards currently, so it would only add more clutter here to make a new variable for it. This may negatively affect the Picomix version, as it's unlikely to get a page for every category like old SI does, but it's the least bad option out of a few tough calls.
Though the categories are empty and still need to be sorted out as of when this was posted, you can find the Picomix leaderboard here: https://www.speedrun.com/Picomix_by_Nusan
