Sure, just none that can be made consistent with Enterprise or Discovery. Especially now, since Burnham very explicitly described how the cloaking device actually works, which makes the "theoretically" no longer appropriate. It is definitely NOT theory any more at this point.
You keep missintg the point. "Theoretically possible"
needn't be in reference to the
concept itself at all—despite the intent at the time that it was—but to the prospect that it's what the Romulans are currently doing. Also, as a general point of semantics, something being known in practical application
doesn't actually abrogate it being described as theoretically possible; that would remain a factual statement in any case. It's not
necessarily synonymous with "possible
only in theory" at all—once again,
despite that being what the writer meant here. There are many theories that could never be determined possible in the first place without at least some degree of practical test.
Spock could just be reminding Kirk that it's possible because Kirk seems to have forgotten (which
might mean Kirk has never seen a cloak in action, but not that
nobody has).
The reason is, the organization that Kirk works for is called "Starfleet," not "UESPA." There are all kinds of headcanon ways you can fit that line into place, but headcanon is not the same thing as continuity.
And to be sure, that's what you're talking about in your "re-interpretation" tango. That's all just head-canon or fanon.
They are BOTH referred to in the dialogue of "Tomorrow Is Yesterday" (TOS), and
together on a plaque prominently displayed in "Demons"/"Terra Prime" (ENT). That much is not headcanon, it's onscreen canon.
(It's also referred to on starship dedication plaques into the 24th century, but those are never clearly seen and full of in-jokes anyway, so I didn't include those.)
Because "warp drive" isn't called "time warp" by anyone else except for Pike, in "the Cage," before the writers had figured out what they wanted the drive system to be called. It's not even called "space warp" anymore; THAT was retconned too after TOS.
There is absolutely no reason why
both can't simply be colloquial shortenings of "spacetime warp drive" or "time-space warp drive"...same as "car"/"auto" from "horseless carriage"/"automobile" or "phone"/"cell" from "cellular telephone" or any number of other real life examples.
Don't confuse headcanon with continuity. Retcons are part of the writers' creative decisions; our fan theories to EXPLAIN the retcons, not so much.
Don't confuse discrepancy with discontinuity, nor fickle behind-the-scenes intent with what is actually on the screen. Anything that
is, and is
left unexplained, is fair game for us fans to come up with our own explanations for (until such time as the writers choose to come up with their own). And as
@zar said above, a retcon doesn't
necessarily erase anything already shown. In fact, ideally, retcons are "supposed" to
not do that. When done "properly," they work by addition, not subtraction. Revealing something new that
alters the way what came before plays and is
viewed and interpreted, but not necessarily
removing it from continuity. There
are retcons which do that—what many would consider inept ones—but that's not the default operating principle involved.
