Hi @btemko
We have reviewed internally and can relay the following:
Regarding PT1 not sending a full chain, this is an oversight on our part we will correct in the near future with a separate PT1 deployment, likely early next year.
For production certificates, I can confirm we send the full chain. You can see this running SSL Labs against one of our production-staging endpoints in Akamai. URL: https://www.ssllabs.com/ssltest/analyze.html?d=e6853.ce.akamaiedge-staging.net. Please recognize that this test is not testing the correct SNI in this test, subsequently resulting in a certificate mismatch error. Ignoring the mismatch, you can see we are presenting the full chain in staging and the same will apply once it's deployed to produciton on the 12th.
