Exactly this.  I left my former $dayjob at the end of November 2017 at a 
$hugecompany building a greenfield network at cloud scale.  It was not 
possible for us to use 32-bit ASNs and do TE'ing the way we wanted to. 
Because it was a $hugecompany, we were able to grab a 16-bit ASN from 
other parts of the company and use it instead.  But we tried 32-bit, and 
it failed to meet our basic network architecture requirements.
