comment Why does Microsoft.com have a TXT record with only a hash code?
@ShaneMadden - There are many experimental RFCs that look at DNS and make use out of txt records that affect email, HTTPS verification, and more. The RFC "MUST" in most of them is to ignore records without the proper prefix or if the data isn't parsable. This may not really cause a negative impact, but new functionality should go through the IAB or IETF. If this is new functionality, I can't find it...

@uSlackr True, but I doubt they would run experiments on a production domain like that. There has to be a public RFC out there somewhere, because doing things like this may break other experimental RFCs.
