libvirt users - Jan 2014 - Will virsh command setvcpus/vcpupin be supported by lxc driver in the future?

Dear member of libvirt team,
I hope the lxc could be dynamically reconfigured, such as the number of vcpu or
vcpu pinning.
According to http://libvirt.org/hvsupport.html , at present,
setvcpus(virDomainSetVcpus) and vcpupin (virDomainGetVcpuPinInfo) are not
supported by lxc driver.
I wonder if these commands will be supported by libvirt in the future?
Best wishes,
Cheng Wang
