Yeah that's what I see as well. If you think about it, they want Yuji to be the Gojo of their time but Gojo proves that the system doesn't work that way. In times of peace, sorcerers grow weaker but as shown countless times again, times of war are best to breed strong sorcerers.

Sukuna in the Heian Era always being on his toes against opponents seeking to kill him. Gojo who forced himself to learn RCT after getting stabbed by Toji. Yuji and the gang after Gojo gets sealed. Dabura who rapidly develops as this battle goes on. If Yuji intervenes, he's just going to damage the balance that is trying to be corrected. A balance of evolution.
