I just tried to install metacatalog (pip install -e .) into a new conda environment and into a new venv environment to test this branch.
In both cases, dependencies are installed but then it does not go any further and hangs in Running setup.py develop for metacatalog. This does not only happen with this branch but also with the main branch.
I will try again tomorrow with a restarted computer, maybe the problem fixes itself...

Okay, the pip install -e . issue was a problem with my computer, the installation went smoothly today.

When trying to activate the standards_export extension with missing dependencies in the environment, a ModuleNotFoundError is produced:

ext.activate_extension('standards_export', 'metacatalog.ext.standards_export', 'StandardsExportExtension')

Running ext.__load_extensions() also produces the expected UserWarning:

@mmaelicke I will approve when you had a look at my previous comment and also confirm that everything works as expected.
