#2: Makes Charlotte Flair feel more relevant

Heading into the match at WrestleMania 35, a lot of the build for the encounter has focused on Becky Lynch and Ronda Rousey, with Charlotte Flair taking something of a backseat.
The decision to add Flair to the match-up angered a lot of the WWE Universe, with many claiming that she has no real rhyme or reason to be there, outside of the fairly flimsy excuse of being the runner-up to Becky Lynch in this year's Women's Royal Rumble encounter.

Well, if nothing else now, having Flair win the SmackDown Women's Championship makes her feel like a more worthy component in the match-up and will help put some of the spotlight on her over the next week or so.
Ultimately, the match is going to be a historic occasion for the WWE, and the company will want as much exposure and hype on the encounter as they can get.
