I would expect any installer to not mess with the ESP. After all the ESP
belongs to the firmware, and multiboot (both multiple Linux versions as
well as other OSes like Windows or BSD) is one main feature of the ESP.

The only exception might be if the ESP is not formatted.

I would say that the ESP is a perfect place for the environment. It's
FAT and it belongs to firmware, so OSes are just expected to *add* their
bootloaders, without touching any other file on it.

Cheers,
