This is John from the Steampipe team -- We're excited to have you contributing to the Steampipe plugin community! We will need to work through the mechanics of how exactly the registry publishing process works, as you are the first external contributor -- We will contact you with more details in this regard.
I took a quick look at your plugin today and had a few items that should be addressed:
$ steampipe query "select * from vault_engines"
+------------+-----------+
| mountpoint | type |
+------------+-----------+
| sys/ | system |
| secret/ | kv |
| identity/ | identity |
| cubbyhole/ | cubbyhole |
+------------+-----------+
