I get the message but if you know how to do things the good way why would you choose cheaper and unreliable solutions? It's just a matter of good FREDding here.
Please note that "escape" is a rather generic word in terms of FREDding. A spacecraft can "escape" by 1) engaging its subspace drives, 2) entering a fighterbay and 3) jumping out without the warp effect. I see 1 can't be done in TVWP, but 2 and 3 are definitely possible ergo your trick will not work on various occasions.
We know that before the very end of FS1 spacecraft couldn't jump from one system to another. Therefore, at some point in the next acts of TVWP, spacecraft will be able to execute jumps from one sector of a system to another.
