Paint.NET :: Alternative Locations For Plugins / Palettes

Nowadays you see programs that install in the 

C:users[username]AppDataLocal or C:Users[username]AppDataRoaming folder, rather than c:program files.

I have mixed feelings about this, because it confuses me where a particular program is installed. But I do understand the benefits.
 
Installation in c:program files requires administrator rights, whereas installation in the AppData can be done without (administrator rights).
 
The same counts for pdn plugins. Currently they need to be placed in c:program filesPaint.Netplugins, which can only be done with administrator rights. In a strictly managed environment I'd need to ask my system administrator to add a few plugins to the pdn install folder structure. (Really, our system administrator can not be bothered with such trivial requests ;-)
 
But if there was a secondary location where plugins can reside,

e.g. C:users[username]AppDataRoamingPaint.NetPlugins

Then any (low-rights) user could add his own plugins to an existing Paint.Net installation without the involvement of an administrator. Wouldn't that be great?
 
Maybe such a scheme could be included in the upcoming PDN 4?
