The Light Speed Barrier has been broken.

Because, if it is true then the conditions of Special Relativity are broken which means you can't use SR to begin with. Unless you only want to accept the theory partly, but then who are you to choose which parts are to be accepted and which not? 

I don't think tachyons are inconsistent with SR. Which principles do you believe are broken by this?

No one knows for certain what the consequences would be, true. I will rephrase it as one of the possible consequences is that signalling backwards could be possible. It depends on the exact mechanism of how they are travelling faster than c.

Most of SR would still hold even if this somehow invalidates it, because all the experiments we've done to confirm SR still stand.

I don't want to talk about tachyons. But if they were tachyon neutrinos, then this whole debacle would've been more about QFT than Einstein's SR.
