Maybe not. But it would remind /me/ (and maybe others) to change to the
prefered setting (whatever the default setting is going to be..)

Same as above. Whatever the setting is going to be, it would be
definitly nice if *grml* would provide a quick way to change the
default. Maybe something like: grml-zsh-share-history enable|disable
(Again, just thinking loud here..)

Ok. See below.

As I tried to say before. I think the "principle of least surprise"
heavily depends on what the user expects (even if all the "other"
shells do not have this default setting). We are talking about grml
users here (at least thats what I thought) and maybe they expect
something *grml* provides (since ages - since when actually?). But
obvioulsy you are not that kind of (grml) user. So there might be no
definite truth here.
As I did not see this discussion about convincing anyone what the
"best" setting is or should be and as you noted that this is not a
vote I do not think I can help anymore in finding the answer what the
default setting should be... It then all leads to the grml-zsh-config
maintainer and what /he/ (or she) thinks whats the least "harmful" for
the grml user...
I surely will be able to live with whatever decision will be made.
All the best!
