Consolidation of plugins arrays and conflicting npm package versions of plugins

[maiertech]

Let's say I use a theme gatsby-theme-something which includes a plugin [email protected]. The plugin comes with some config options in the theme's gatsby-config.js. Now I include the theme in my website.

First scenario: I also include the plugin in my site, but at a newer version, say [email protected], with the same config as in the theme. Will Gatsby deduplicate the plugin and which version of the plugin will it use?

Second scenario: I include the plugin at a newer version, say [email protected], and with different options Will Gatsby process the plugin twice? And at which version?

Where can I find out more on how Gatsby consolidates different gatsby-config.js files when I use one or more themes, possibly nested? I'm having a hard time understanding how Gatsby consolidates the plugins arrays from different themes and how it handles conflicting versions of the same plugins?
