So, it's been a while since this last got feedback.
It is a highly dangerous idea to be doing what plugman does; and therefore whilst most developers would be willing to code a plugin that breaks your server - We do not wish to have such a negative impact on servers.
We will not be coding such a plugin at this time, however we have made note of the WorldEdit limit idea and may work on that in the future.
Thank you for this suggestion. LOCKED.
