I also see some possible flaws just by looking at it.
The plug thingy since it's attached to the front of the tank, the whole thing can pop out when you're trying to open it up to refill the tank.
You are right, best way is imho to remove the plug entirely to refill. Otherwise it may fall down to disappear, of course, somewhere behind or under some furniture where it would stay hidden for a long time...
Plus, it stays in the way when you refill, not very handy. Plus, I think it's best to open the two holes to let air escape when refilling.
And it can be reinstalled easily. Although maybe too easily, but for the moment on my tank, it stays in place, no leaks.
