U-Boot and PlanetCore can't share the same environment but
board-specific code in U-Boot can use PlanetCore environment to
initialise U-Boot's one.

No, if the environment is not in flash this problem does not exist but
the EEPROM is too small for U-Boot's environment (and Wolfgang always
advises against using EEPROM for environment:).

There will be no single binary image for all boards but can be single
source which also reduces maintenance efforts.
