Jetpack is being deprecated on VIP Go

VIP Go users who want to run search in any kind of custom way (including es-wp-query) are being switched over to the Enterprise Search solution there. See [their recent lobby post](https://lobby.vip.wordpress.com/2022/02/02/enterprise-search-as-default-elasticsearch-solution/) on this.

I tried using the `WP_Com` adapter to see if it might work in the VIP Go environment, but it results in the following error:

```zsh

```

I'm assuming this means that the new Enterprise solution will need its own adapter. Are there already plans to make one? I haven't really investigated what it would take to make one and wanted to see if it's already coming.
