What if Boot0 and Boot1 are not connected

Hello,
I'm developing a board for a robot and I'm using STM32.
I'll need to use the BOOT pins to select which boot mode will i use, and potentially I'll need all the boot modes since I'll have to embed different programs and debug them.

To select boot mode I'm using jumpers to select VCC or GND for each on the BOOT pins.

I'm asking what will hapen if i forget putting jumpers and those pins will be just not connected?

Should i use a pulldown to force them to 0 if there are no jumpers?
