Technically that power strategy works but in the real world clients don't want to wait a long interval to connect and boosting the power on a short interval creates more RF chaos than you are trying to solve.
There are many standards to assist in roaming such as .11k, v, and r. Particularly for mesh nodes s. In the end the strategy used in Wi-Fi is that the end station is the one that decides when to roam and why. Again it comes down to the client knows more information about what it could connect to and when it makes sense for it to roam than the AP could. The AP can just send hints that it'd like it off of it for other clients benefits.
Many Enterprise systems come with the ability to tune power the same way they can automatically tune channels. Usually they tune against other APs rather than clients since AP positions and emissions are much more static and controlled by the same system (normally).
