I do not understand why Sakura spent 3 years learning such an ineffective technique. The main function of the combo of Ninpō Sōzō Saisei - Byakugō in Jutsu is to ensure a continuous regeneration, however, the regenerative capacity does not seem so impressive.
There are so many destructive Jutsus that could reduce Sakura to dust or even dismember her without difficulty. This Jutsu is not able to deal with a decapitation or even with a destructive Ninjutsu.
Sakura needing to be saved by Kakashi in the lava dimension shows that this Jutsu does not guarantee any immortality in battle. In fact, it only prolongs the user's life against low-level opponents. Even against Kage Level Ninjas, this Jutsu can still be overcome.
It is undoubtedly disappointing that such a technique does not meet the expectations placed on it. It still has a disadvantageous concept to the user (Cell Division). In short, the pinnacle of Medical Ninjutsu is not at all impressive and Kishimoto is rubbish when it comes to female characters.
