Never ending PBW games because of Stellar manip

[trooper]

Imagine two Groups of allied empires in an advanced PBW game. Both of them have stellar manip and both of them have cut their WP to the ennemy and protect their systems with shields facilities.

This type of game may not end, as any attack can be prevented or neutralized by cuting a warp point... Ever experienced that in PBW ? Do player declare a draw match in that situation ?
