Ooo... I needed this, cause I've had a random idea bouncing around my head for a while...
Anyways, I was reading one of Syaoran's flashback chapters, and
here, I found it a bit odd that her parents called her Sakura-hime (and we know Sakura's not her real name); it seemed more like a title than a name. Anyways, when we found out that Clow was actually the future of Acid Tokyo, and since Sakura gave so much to the inhabitants in the Tokyo Arc, I thought, wouldn't the inhabitants of Acid Tokyo want to remember her by something?
Anyways, I hypothesised that 'Sakura-hime' has been passed down from the time of Acid Tokyo as like, a title that perhaps the early royalty used to honour the sacrifice she paid.
So all I was getting to at was: isn't it interesting that Sakura's name (well, the one she's known by) was derived, from well, herself?
Well, that was my two cents. It feels better to have said it. XD
