I already commented on this one. I get the feeling it isn't "good looking forward", just because of the number of times something was presented as "impossible" to Naruto, and having him do it anyways.
With rules set up to keep Sakura out of the fight, Kishimoto is just setting up an obstacle for Sakura overcome. (But I've been wrong before.)
But nothing is being presented as impossible here.
This rule isn't some archaic tradition that's unfair, unjust, or based on outdated assumptions about people. It's not the Hyuuga branding, it's not something that makes her a loser or even really holds her back. It's not portrayed as something she can't do.
This rule make sense. A medic in the field fighting is (1) a medic not providing the support services they were trained specifically to provide (services that Kishimoto has gone out of his way to portray as valuable) and (2) increase the odds they will die simply by being there and a dead medic is also one not providing those services.
I would doubt that Tsunade put that in place to simply hold Sakura back or because she thought medic-nin we incapable of fighting. In fact, the rule says absolutely nothing about that. I believe that set has far more to do with the value Tsunade places on that skill set (given her history) and is not meant to say anything at all about fighting ability. In her younger days ninja placed no value on medics and all value on fighting. It was what she fought to change.
What's rather odd about the inclusion of the rules now is that Sakura had already violated them before they were even stated. Unless Sakura knew the technique prior to fighting Sasori, she violated that ages ago. She has tried to engaged Sasuke twice.
So...what's she overcoming? She blew right past that the moment she fought Sasori.
Kishimoto could do what you say, but I wouldn't be terribly impressed with her overcoming an obstacle that isn't one and that she has already overcome.

I think Tsunade will be able to hang on a while longer, as she's using her regenerative jutsu. But she won't last much longer after the fight, as the jutsu reduces her lifespan. I'm hoping she'll be able to hang on long enough to have one last meeting with Naruto and Sakura!
If she dies, I think she will live long enough to provide to transfer the title of Hokage. Even though the village feelings to Naruto have changed, technically speaking, leaves a vacuum of power that could be filled in a way she doesn't want. Remember Danzou? The other, bigger reason, is great drama and symbolic toward one of his central themes.
