Why else - a hundred years after the electron was discovered - do we still
use conventional currents?

Maybe because we realize that BOTH kinds of charged objects can move?
And that Right Hand Rules work for positive charge in motion and Left
Hand Rules work for negatively charged things moving.

Modern semiconductor explanations need 'holes' as much as they need
'electrons'.
