Yes it is. The plugin has been created primarily as a helper plugin for Bricks and Oxygen site builders. It will grow organically over time. This plugin will remain free.
As the plugin is free then the support is necessarily limited.
We will:
Several of the shortcodes are specifically designed for use in Brikcs components and Oxygen re-usable parts.
The postmeta related shortcodes can be used to include post meta information in the post header such as the post published date, post modified date, the author link and the post edit link. The copyright shortcode is used in the Oxygen footer reusuable part which appears at the foot of each page.
The other shortcodes will be made available as Gutenberg blocks since they are largely for use directly in the page content. These include shortcodes for Wistia videos and Pastebin code inserts.
