Well, if those folder contain calender data that the users needs on a daily 
basis, this user will miss them on the default sync as well.

I have the opposite impression and I am trying to understand what is going on.

Overall I think it is more simple to have one rule for each folder
and do not depend on if the folder is part of the inbox or not.
(This is not easy to determine on some IMAP layouts, btw.)

You are saying that people will want to have a sync by default, but for 
security reasons that is not possible for all folders as we have established.
So I am proposing a scheme which keeps one rule for all folders
which includes on activation mechanism with a real Kolab Client, e.g the web 
client. Otherwise I believe quite a few people will miss their events from 
other folders.

There is just one potential setting we were talking about: 
hierarchical or flat syn mode.
And this is not per folder, but per device.
So it should not be in every folder otherwise you get a conflict if folder A 
says hierarchical and folder B says flat.

You would need to define the precise folder it is in and this has to exists
for stuff to work. A candidate would be the event.default folder.
If this is just one setting we are talking about, I think that using two 
different URLs could still be an option.

The suggestion of the activation mode might possibly solve this for good
as well. I think of the following steps:
a) enter the right URL and setting in your phone, try to sync
b) zpush does not have any folder with the annotation thus, it will syn back 
with a welcome event or task or contact: saying: please activate your folder 
on url demo.kolab.org/activatezpush. But zpush temporarily remembers the phone 
data.

c) User goes there, get presented a selection of phones that have tried to 
sync in the past (and had the credentials).And of course all folder where 
there is access. User can now initiative the sync, which will write the 
annotation

d) next phone just syncs like the first phone by default. zpush again 
remembers the phone data.

e) User can go to the client to adjust the folder and now has the selection of 
phones,  can be disabled for folders that have been enabled before.

Best,
Bernhard
