Suppress warnings for 3rd party directives

[mason3k]

I am looking for the recommended way to resolve a build warning when the directive comes from a separate 3rd-party extension.

Even when using the only directive to house the third-party extension, I still get the warning for, for example, when running the html builder with a directive meant for the confluence builder:
WARNING: Unknown directive type: 'confluence_toc' [myst.directive_unknown]

I know that I could suppress the warning in conf.py but is there a way to handle these spurious errors better without suppressing real errors?

I assume only doesn't work because it is mostly concerned with filtering the output in a "post" hook:
sphinx-doc/sphinx#1420

Heya, yeh exactly everything in the only is still parsed, but just filtered out in the outputs.

I would ask why is the confluence_toc directive not loaded?
All 3rd-party libraries should still be loaded, irrespective of what your output is.

Otherwise, you could always create a "dummy" directive in your conf.py
