Still that doesn't clarify if there can be multiple ones.
I just had a first talk with Raymund (will continue; he had to do something
urgent in between):
There can be any number of EFI system partitions. This is normally not a
problem - except sometimes for Windows, so Raymund said.
Which bootloader will be used when there are multiple ESPs seems to be a
problem, though; basically, the admin should explicitly specify that in NVRAM
(?) variables. If he doesn't do that (or doesn't even know that this option
exists), according to Raymund it depends on the EFI implementation of that
machine; different vendors seem to use different strategies here.

Tentative outlook - this will need further discussion: It might be necessary
to handle this differently depending on whether or not there is a Windows
partition on the system; it might be useful to reuse the existing ESP in that
case to avoid confusing Windows (or a non-expert user who doesn't know how to
set those NVRAM variables).
Raymund is really busy before tomorrow's deadline; he promised we will
continue with this next week.
Kind regards
