Kon-El, Steel and the remnants of the JLI (from that era in the early 90s) were all inspired by Superman's heroic sacrifice in the Death of Superman, Reign of Superman and World Without Superman arcs.
Some others would be, Kimiyo Hoshi during COIE, Mon-El (way back on Superboy #18 1961), the original Legion of Superheroes of course (although Supes lost his connection with them after COIE 1985 and never really recovered a good relationship with them. Despite Johns revival of them post-Infinite Crisis).
I lean towards this being a conscious effort. I listed the above instances of Superman inspiring people. But then you look at Geoff Johns' works from 2005 and 2007, lampooning the standards DC advertises and states Superman stands for.
A big writer like Johns; who is now Chief Creative Officer at DC comics, producer for the DC shows (mainly Flash and Supergirl), a producer for the DCEU movies and was recently appointed as President of DC Entertainment, and Editor and Chief Dan Didio gave the green light on the above panels and corresponding stories. Making Superman look like a weak and foolish. I can't remember a single person or instance of Superman inspiring anyone during the New 52 and he was everywhere on those books.
Superman
Action Comics Superman
Batman/Superman
Superman/Wonder Woman
Justice League and Justice League of America (not the Amanda Waller team)
You look at the big arcs and events from that era.
Savage Dawn
Truth
Convergence
Doomed
Future's End
Trinity War
Unchained
You notice that Superman had nothing to do, but show up and punch things or be taken out of the action by the writers somehow. Like the Injustice League and Amazo Virus arcs when Lex joins the League. It's about Batman and Lex dueling personalities, rather than Superman engaging Lex. Batman saves the day with compassion against Jessica Cruz, and it's Bruce and Lex who solve the Amazo Virus problem. In fact, none of Johns' JL were about Superman.
This can't be on accident. The writers just don't seem to care to make Superman look good.
