That was one of many factors that I think the invocation was necessary. Th residents, as well as affected businesses, in Ottawa were left to fend for themselves as leadership(including the police) could not end the occupation of the downtown core. There were multiple blockades of varying degrees that were also problematic. What came out of the Coutts blockade was worrisome to say the least. The one at the Ambassador Bridge was cleared but who knew if people would come back or setup elsewhere. No one knew how things would play out at the time but there was a lot of concern across Canada. Even by the judge's admission, he may have advised the same conclusion the government decided on.
At the end of the day I agree with the public inquiry that didn't find it unreasonable and perhaps revisions to the Emergencies Act is something to consider.
The dev mentioned they're working on this. If you haven't already, you may want to enroll in the beta builds since it'll be released there first. And they're pretty stable.
