23AF HORIZONTAL LINE EXTENSION: glyph or variation selector?

Current (and 7.0.0-tobe) versions do not say much:

        * used for extension of arrows
        x (vertical line extension - 23D0)

If it is intended to be a variation selector (possibly prepended
instead of appended!), then using it with ⇒ should give longer double
arrow, and using it with ↦ should give a longer variant of ↦.

If it is a glyph, then what is the difference with U+2500 ─ ? It
looks like then any vertical-positioning distinction is trivially
understood from context…

Any thoughts? Thanks,
