Not at all. There's plenty of room for new infoinfo, just not continuity-shattering things like instant jump drive.
The spore drive doesn't violate continuity
The federation is nearly conquered at the same level as TNG "Yesterday Enterprise". Then some how Discovery connects to TOS, TNG, DS9, and Voyager without a mention of those events?
Neither does this.
You know why? Because it was never established that the federation didn't develop a spore hub drive and it was never fully established how bad the conflict with the klingons got pre-tos. Just because no one has mentioned the spore drive or the near disastrous outcome of the klingon war doesn't mean they didn't exist.
People need to stop confusing 'continuity violations' with 'things they don't like'
