Cloudflare has been doing this for a while, so that their customers won't be "limited by the DNS specifications (RFCs)" <rolls eyes>. Having done that, they were compelled to offer another service -- so-called "CNAME flattening" -- to fix the brokenness that's caused by their base offering.
I think Akamai also offers something similar.

That doesn't seem valid to begin with. The .COM zone has delegation NS records for sharepoint.com. Having a CNAME record for the same name is wrong.
