It's little questions like this that I want answered, but I fear that it's just going to be glossed over. Hopefully we've earned an explanation after all these faithful years.

Peter ceased to exist after the 3rd season, and the show went to great lengths in the 4th to show how much that changed the world..Plus it has been said many times that the simplest action(ie killing a fly) can resonate in such a way to change the entire timeline, So the observers were afraid to do much more than, well, observe, before the invasion. Remember its the original timeline they wanted, where there was no interaction between universes.But then September interfered and changed everything. They wanted to get back to the timeline there was before September saved Peter but were hesitant to do too much out of fear of mucking things up even further. So Peter is still alive but by the end of S4 the portal has been closed and there is no threat of contact between the universes. From the Observers point of view its not perfect, but close enough tp the original timeline that they can go through with their original plan. But until they actually invade they didn't want6 to do anything like killing Peter out of fear that would change things even further. They have already seen what chaos can result when they interfere.
Works for me anyways. YMMV of course.
