Google has been recommending for years and years to use RSS feeds and PubSubHubbub to help Google index new content quickly, in addition to using XML Sitemaps.
Truth is, I am a bit surprised they still recommend it but they do.
John Mueller from Google said on Twitter, "RSS + PubSubHubbub & Search Console submission of the feed will get it indexed quickly too."
He said this in response to a question about indexing was asked on Twitter:
@onreact_com Yes. RSS + https://t.co/Ky0cENOh6m + Search Console submission of the feed will get it indexed quickly too.

So it can't hurt to support it being that Google has been recommending it for at least 3-4 years, probably longer, and it still is recommended.
