I understand the concern. But on the flipside, the Sans/Alphys pair (which is the most plausible pair of main characters) is built upon several layers of speculation: in order to get to the conclusion, we need to presume that they both knew Gaster, which requires that they have a deeper connection than either lets on, and that they collaborate or have collaborated on scientific projects. But the closest we get to any evidence is the existence of the Gaster Blaster (which Papyrus potentially has as well, raising the question of how he got it), and Sans's research into timelines (which is usually assumed to be a continuation of Gaster's research, but "the creation" that Gaster was working on is never stated to have anything to do with time). We're missing several steps.

I feel it might also be worthwhile to raise the point that the followers say that it takes a long time for Asgore to appoint a new royal scientist. What "a long time" means is certainly unclear, and thus cannot serve as definitive proof, but can serve as speculative evidence against the pair being any of the main characters.
