Is GlobExcludeDefault used anywhere else? Can we just add **/_category_.{json,yaml,yml} to it so we don’t need to do the filtering or pushing of the _spec_ files?

[baptisteArno]

True! That should work just fine 👌

[bourdakos1]

Hmm it looks like the demo isn’t picking up the _spec_ 🤔

I didn’t realize the default glob is coming directly from Docusaurus, so maybe they changed their glob in a newer version?

[baptisteArno]

That's a mystery for me, I checked the file history that contains the GlobIgnore pattern, it has never changed 🤔 I'll investigate and let you know

[baptisteArno]

It's this pattern "**/_*/**" that excludes _spec_.* files.

Let's just not rely on GlobExcludeDefault for this source fetching. It's useless.
