Well, if you put it that way, sure. However I don't see how that could
happen: LibVLC and the GUI both only allow a single track to be selected
or not. There are no provisions for a track to be selected more than
once at a time.
I know only one way to achieve that: combining sout_duplicate with
sout_display. But then it already works without code changes.

It seems to me that this "duplication" feature is orthogonal to the
"multiple simultaneous subtitle" feature. I would suggest first getting
multiple different subtitle tracks to work. You can always add
