Adding AWS Personalize Resources

I have started to develop the resources for AWS Personalize however the turn around time on PRs is very slow. I opened https://github.com/terraform-providers/terraform-provider-aws/pull/10683 16 days ago and it is the first resource of several. The previous PR (#9794) to add the dependencies took 14 days.

Is there anyway to speed this process up? Might it better to work on a larger multi-resource PR even if the patch review is longer? I’m also looking at developing the Forecast resources as the APIs are similar so the same thoughts will likely apply.
