Set repository_meta = "local" by default?

[wlandau]

repository_meta is an option in tar_option_set(). targets pipelines with repository_meta = "aws" (or "gcp") periodically upload _targets/meta/meta and other metadata (even debugging workspaces in targets >= 1.10.1) to a bucket in the cloud while the pipeline is running. The idea is to allow targets pipelines to run non-interactively, i.e. in an AWS Batch job, and allow the user's interactive session to download and view the data and metadata.

The current default for repository_meta is the same as repository, which means that repository = "aws" will upload both data and metadata to the cloud if the user does not manually set tar_option_set(repository_meta = "local").

In other words, pipelines opt into uploading metadata to buckets by default. On reflection, I am wondering if repository_meta = "local" would be a better default. targets pipelines are most convenient when you have an interactive R session (e.g. in Posit Workbench), the main process runs in the R console or an RStudio Background Job, and parallel workers run on Batch as needed. In other words, the pipeline is part of the interactive Workbench session, and users can stay in the comfort of their own familiar environment. And from a security standpoint, this seems feasible because Workbench can take care of AWS credentials behind the scenes.

If you use targets with AWS or GCP, what do you think? Should the default repository_meta be "local"?
