#1. More possibilities heading into WrestleMania

As amazing as it would be to see Becky Lynch hold the Raw Women's Title for an entire calendar year, it would also be one of the most predictable options possible. In fact, most fans assume that Lynch will do so at this point, especially with WrestleMania only a few months away, which is why the company needs to shock everyone.
Not only will this serve as a ratings boost for WWE and breath new life into Lynch's character, it will also open up a lot of doors for WrestleMania 36. It will even give the rest of the Raw women's division a chance to secure a lucrative spot for WrestleMania 36, which could really up the unpredictability factor.

In all honesty, WWE needs to do better than just having someone hold onto the Raw Women's Title for an entire calendar year. Furthermore, Lynch doesn't even need the title at this point in her career and there would be no suitable opponents for her to face at WrestleMania 36 anyway.
