The system forbids reverse paths (../) in Less @import statements so how can an extension share its Less file between frontend and backend?

Line 79 in 4499554

throw new \InvalidArgumentException("File path '{$filePath}' is forbidden for security reasons.");

I found a solution: the common Less files can be placed into the extension's web/base folder and then referred from both the web/frontend and web/adminhtml folders.

Too quick for me! Yes, base is "global", not per area. It is designed for sharing files between different areas like what you were after.
