Not sure why they were removed but in the past, root certificates are 
removed due to problems with the certificate authorities that mean their 
signatures no longer mean the sites are who they say there.

That's the problem with PKI. When you can't trust the root, you can't 
sign any certificate down the chain from the root.

Unfortunately DANE is not yet supported by browsers.

But anyway, does the changelog indicate why the certs were removed?

It may be a good thing - protecting you from potential MITM when you 
otherwise would have the assumption that the site is valid because it 
has a cert.

I know digicert specifically has had problems before resulting in 
fraudulent certificates being issued.

Hopefully the industry can move to DANE and make blind trust a thing of 
the past.
