The existence of characters that need this much work to explain suggests to be that unicode is bloated. Not the only thing that suggests that, either.
The stated goal of Unicode is to support every past and present writing system in world world. Say what you will about that but I think just because a symbol's meaning might be obscure to us doesn't mean it isn't useful to someone else.
That’s unavoidable given the goal: Unicode provides a unique number for every character, no matter what the platform, no matter what the program, no matter what the language.
