The Prime Directive isn't just ideological–there's all sorts of possible consequences of using technology you do not understand. Earth and Vulcan have mass graves that are a testament to the misuse of technology whose scientific principles were understood. If the Federation embraced hypocrisy to benefit from a few extra toys...
And, frankly, I'm not sure most Vulcans on the science council will think thirty years is that long to wait for batmobile armour.
Starfleet ethics aside, I also would rather Timefleet have deleted Admiral Janeway because, well... batmobile armour. Ugh.
*The fact that Janeway needed to buy off some Klingon to get the Time Tunnel means that someone is keeping the gravity-whoosh-time-warp procedure under very tight wraps. Probably because of the threat of that very thing...
