All plugins loaded as themes ?

[Alessandro-4EYES]

Description

When running gatsby develop, all plugins are loaded as themes. The debugger tries to search for component-shadowing in all the plugin directories for name "default-site-plugin" which does not exist.

Expected result

Do not load themes as no theme is used.

Actual result

A Theme "default-site-plugin" is used.

What exact issue do you have?

Hey, this discussion is a little old now, but I wanted to see if there is a way to opt out of this behavior?

The problem is that loading all plugins as themes increases build time. Sometimes by just a few ms each, but, collectively it seems like it could be a lot? Here is a small sample of some of my components, but there are many more

I don't currently use any of Gatsby's theming capabilities in my project, so it seems like checking for these files is unnecessary? Thanks for taking a look.
