I think most people have already argued for the narrative consistency of Homura's choice. Here, I'll instead be arguing that the Rebellion ending is plausible according to in-universe logic, even without the Wraith arc. To do so, I'll try to address some major points of logical confusion/criticism of the ending:

How did Homura gain the ability to split the Law of Cycles?

This may be a misconception about what it actually means to split the Law of Cycles. As a witch, Homura has the power of memory manipulation, which is used throughout Rebellion. She uses this power to steal Madokami’s memories. However, Madokami’s memories are the only thing that has remained human about her. So by stealing her memories, Homura is effectively stealing the human Madoka, splitting her off from her divine form.

How did Homura remain a witch?

The obvious answer is that Kyubey’s isolation chamber weakened Madokami enough for her to more easily lose her memories, allowing Homura to develop witch powers without losing her sentience (soul gem). 
However, the answer might be more fundamental than that. Madokami prevents the birth of witches by resolving the despair of magical girls and reconciling them with their wishes. For instance, Madoka reaffirms Sayaka’s wish by showing her Kyosuke’s performance. In the flower scene, when Madoka admits to not wanting to leave her current life, she unintentionally reaffirms Homura’s wish to protect her. Yet Madokami’s very existence defies Homura’s wish, and there is no way to reconcile the two. This might be what Homura refers to when she says her feeling (i.e. love) is hers alone; she’s the only one whose curse cannot be resolved by Madokami.

How did Homura steal a fully-powered Madokami’s memories AND expand her dream world to encompass the entire universe?

The above explanations alone might seem insufficient to explain how Homura can usurp a literal god. Fortunately, there are many possible ways to make it plausible:

1. Regardless of power, any witch would be able to suppress the Law of Cycles using memory manipulation, but Homura is the only witch that can exist up until that point. Splitting Madokami then fundamentally changes the universe’s laws to preserve Madoka's existence.
2. Witches concentrate collective negative emotion, preventing the birth of new wraiths. Homura, as the singular witch, concentrates the entire world’s negative emotions into herself, becoming powerful enough to suppress the Law of Cycles.
3. Homura’s wish to save Madoka makes the Law of Cycles a paradox. The ability to break a universal law gives her enough karmic weight to suppress it.

In addition, we know for sure that:

• The Law of Cycles still exists and almost manifests itself, meaning Homura’s power doesn’t actually need to be on the same level as the Law of Cycles but needs to be just enough to superficially suppress it.
• The Law of Cycles still got rid of all past witches, so Homura’s dream world isn’t timeless and nor did she fully reset the universe. If this weren’t the case, then wraiths wouldn’t still exist. This also means that Homura is the only witch in existence at least as of becoming one.

All of this to say, there are many ways for Walpurgisnacht Rising to directly or implicitly provide plausibility to the Rebellion ending, but I guess we'll wait and see.
