To hopefully awaken and further inform the discussion around the ANAME
and HTTP draft specifications that have been put forward, I've done some
further analysis across the Alexa top 1 million domains - my initial
findings are available at https://thpts.github.io/a_or_cname/ .
A brief summary of what I have found across the entire dataset:
* 51% of www records return an A record
* 47% of www records return a CNAME
* 64% of those point www back to apex (i.e. www.example.com. IN CNAME
example.com.)
* 17 www records are DNAME
Any feedback, corrections, and suggestions would be greatly appreciated.

That may be the case from your own (presumably anecdotal)
experience, however I took the Alexa top 1 million websites and
queried for A* and CNAME against the www records for the top 10 000
domains. What I found is that approximately 44% returned CNAME
records, 56% returning A records.

* I realise that I could have added AAAA. My presumption is that the
top 10k websites are not v6 only and at least have an A record in place.

In fact if you look at the DNS records some big Internet companies
they rarely use CNAMEs for www but instead you'll see an A record,
that might
be even backed by a proprietary ANAME solution.
