Short answer: No.
Slightly longer answer: We don't allow it because of security implications. This is in regards to plugins and that they're closed source (so we don't know what code they're running), they're from potentially unreputable sources, and ArkAPI doesn't limit what they can do last we spoke to the developer of ArkAPI, so theoretically you could access other files of the machines that your server is running on, outside of what we normally allow (i.e. your server saves/configs etc).
If that's no longer the case, by all means please let us know, we'll take a look into it again.
