Support for deploymentsettings when using pac pipeline deploy

[nitkavd]

The pac solution import supports passing the settings file to setup environment variables and connections (--settings-file).
Some tenants are configured to run with the Power Platform pipelines, and all deploys should be done using these pipelines, so we cannot use the pac solution import approach.
It seems that the pipeline deploy UI (and the pipelines framework) support the use of deploymentsettings. When entering the configuration in the UI upon deploy, the settings seem to be persisted in a deploymentsettings field of the pipeline run. Passing the deploymentsettings is not yet available in the CLI.

Can we expect this addition? Is there a workaround, while still using pac pipeline deploy?
