A Question about civilizations that have own versions of warp drive

If a civilization has developed their own version of warp drive or a sort of work around does that still count as warp drive according to the rules in UP?

For example since Vaadwaur and Turei ships use underspace corridors (which functions like warp drive) to travel would that count as warp drive and add points to their ship’s systems total (especially if you want to update the Vaadwaur assualt fighter system’s total based on events in STO)?

Is it really the warp drive that counts?
Or do we look for interstellar travel with non-conventional drives

In regards to non-UE, Federation, or Klingon vessels of any size you are supposed to “reduce the number of System Points by 1 for each 50 years prior to this time to represent the Confederacy of Vulcan (and by extension Romulan Empire’s) extremely long history of warp capable flight, and the Vulcans sharing technology (or having it stolen and reverse engineered) with the nearby polities on Andor and Tellar Prime. After 2160, technology matches that of the overall Federation.”

And while it says after 2160, technology matches that of the Federation, the Vaadwaur and Turei are exceptions due to their use of underspace corridors instead of warp drive. Another exception in regards to technology matching the Federation, is the Talarian Q’Maire which possesses warp drive but uses outdated weaponry and technology that matches 20th century Earth.
