We would need to prepare for a future where we need yet another special thing to be expanded, and it will quickly become cryptic if you said "~/ is HOME, ~USER/ is USER's HOME, ~~/ is runtime prefix, and ~~~/ is this new thing...". ~runtime_prefix~/ (i.e. carve out the namespace for USERNAME by reserving any names that ends with a tilde) may be a viable way to do this, though. It is just as good as your other idea, <runtime_prefix>, in an earlier message.
