Interest

For development : I use symbolic link for all of my plugin then can test on different LimeSurvey version (and all of my repo are oin a specific directory)
If you have 2 instances or more on same server: you can use same files for different instance (you don't do it for limeservices ?)

And there are no reason it was not allowed

Security is certainly a reason.

? Why ? It's my choice to get by link and it's only accessible by server admin

Symbolic link work for plugins and for the Survey theme.

It's OK if i fix it ?
