What bad would happen if you provide to users way to use custom storage 
plugins without having to fix PVE sources on every libpve-storage-perl 
package update?

Also such autoloading would allow you to split plugins into separate 
packages, with own dependencies, thus allowing to install them 
automatically if user wants some plugin, and not to overload 
libpve-storage-perl with dependencies, which most users will not need. 
Like move RBDPlugin into libpve-storage-rbd-perl and set ceph into 
dependency. Or libpve-storage-glusterfs-perl and glusterfs-client. And 
so on.

And users would share their plugins in own packages, which you not have 
to support, but which could significantly empower PVE storage capabilities.
