The primary reason is the ease of post processing the image, to clean it up before uploading it to OpenStack Glance.
I do it this way because of the requirements from my stakeholders needing images setup a specific way, as close to upstream operating system default minimal installations.
Being totally honest, I have yet to fully look into fai to see if it is a potential replacement that I can use.
I originally started with custom python scripts that wrapped the hypervisor CLIs.

not interesting for me since I need to script all the process.

You speaks about packer, but the initial cloud images are generated with fai.
Is there a reason to prefer packer instead of fai for this second customization process.
this is realy a naiv question, do not suppose a bad faith from my part.
