STM32F303VCT6 don't have MCO-PLL divider ?
but gpio have 50 MHz band.; how i output 72 MHz ?

You can output SYSCLK instead of PLLCLK you avoid the divider. Note than 72 MHz is above the specification on GPIO pins, but it may work to some extent.

this is a search for crutches. definitely a flaw.

You're saying that MCOPRE not existing on the STM32F303VCT6 is a flaw? I mean, you can wish it was another way, but it's described correctly in the RM so what exactly are you expecting here?

I think that the MCU should have a divider, for example, to output a frequency below 2 MHz when the outputs are set to low speed. And the source may well be PLL. note that SYSCLK can also be 72 MHz.
before, I didn't understand why people study other MCUs when there is such a cool ST. now I want to see documents from other manufacturers.

You can output PLLCLK/N through TIM1/TIM8.
