bpdu tunnelling required for stretched L2 net over λ fiber?

Hello,

Might be a silly question, but we are stretching a vlan across 2 geographically separate sites, connected by a 10G "ethernet private line" wave service from our ISP.

given that this is a wavelength service is it required to implement bpdu tunneling as a best practice? both sides connect to a HP 5940AF.

Thanks for any input.
