Terraform and the PHB
Which all begs the question, why would you use this rather than just writing Terraform?
And I suspect the answer is that the PHB has heard of Microsoft and hasn't heard of Hashicorp. We all know the type, claim they're "risk averse" as an excuse for running hardware and software that's near or past its end of support. Believe that nobody got fired for buying Microsoft (or IBM). When the head of development comes to him for budget, he'll go over the proposal and believe he's adding value by insisting they use Bicep rather than Terraform.
At the same time there will be analyst charts showing a tick in a box for AWS with CloudFormation and a tentative tick in the same box for Bicep. The fact that most developers don't use either doesn't stop it being a "feature gap" for Azure.
