I think the whole canon/non-canon is incredibly frustrating; even the developers and writers seem unsure and finicky about the whole thing, believing that fans should just believe what they like about the backstory.
There are two reasons for this. Firstly, the story telling method itself. With the Half-Life series, Valve has always focused on 'less is more', where there's no tangible, traditional narrative to follow. There's no 'big reveal', or points where things are explained to the player. This is partially due to them wanting to keep the game from Gordon's perspective. What Gordon knows is all you're supposed to know, and thus Gordon only knows what he is told. Everything else, everything you work out, is also Gordon working it out. Valve likes an element of vagueness and discovery to their plots. Stuff for people to think over. Surprisingly, a lot can be worked out, even if nothing is explicitly told to the player. For example, it's never explained what the Combine want or why they're on Earth, but you can work it out if you listen to Breen's speeches and note the design of their military force, along with their behaviour.
The second reason is that, at the end of the day, Valve makes video games first, stories second. They're open to restructuring and rebuilding the plot to better fit game mechanics if they need to. Establishing a strict canon runs the risk of fucking up later down the track when you need to change that canonical element, something much easier to do if that element was originally vague. Valve constructs plot elements around the game itself. Like the slow teleport. That became a somewhat important element of the Combine's technology, and a massive story point to advance Alyx and Gordon to the final push by the resistance. But the only reason it came about is because Valve ran out of time and couldn't work out how to get Gordon and Alyx from Nova Prospekt back to Kleiner's lab and logically advance the story towards a war. The levels weren't there, nor the time development. So they forced in the slow teleport idea to fill that hole.
