@Sieg this breaks extending the flow theme with child themes when importing less files from the parent theme in the child theme.
Also reusing javascripts from parent theme will not work anymore.

If this is done by purpose how should child-themes be set-up now?

composer update|install --prefer-source

@kaluzki yes thx this would bring the build folder to vendor dir.

However overriding styles in the child theme would mean a lot of path changing in scss files or copying the build folder manually to the child theme. (Since the grunt task would need to be copied anyway)

Then i would rather fork wave theme and use the fork as main theme, no child themes.
