There is no "movement". It has long been one of the in-use spellings, for
when people wanted to disambiguate and the new capital version didn't yet
exist, or for whatever reasons if in new publications.

Characters can be displayed in a variety of glyphs, but claiming that even
if it uses a glyph in the range of character x it is "intended" to actually
be character y which has a different range of glyphs, destroys its
character identity.
If you do that, then all bets are off. Who is to say that any of the
uppercase-looking things are actually glyphs for uppercase characters? They
might as well be glyph variations for their lowercase characters.
