The general Ada term is "visible" comprising "directly visible", RM 8.3(2).

Direct visibility in this context is use-visibility in contrast to visibili=
ty by selection (selected_component). So I do not understand what you are t=
rying to say. Would you favor use-clauses everywhere, i.e. (not Ada) an imp=
lied use-clause with any with-clause? But for resolving visibility conflict=
s, we need selector_names, so we need a term for this kind of visibility.
