Is Stapler Facet even needed?

[duemir]

What feature do you want to see added?

Stapler Facet is empty. It does not contain any framework-specific settings that need to be configured on the module.
It is essentially just a toggle for a few features.
Is it even necessary?

There are currently no facet-specific configs and no facet-based tool windows. As stated above, it is used as a flag in JEXL checker, but that is about it.

Not really needed a the moment, it seems, but can there be a reason to use it?

Currently Facet is used only here:

idea-stapler-plugin/src/main/java/org/kohsuke/stapler/idea/LocalXmlInspectionTool.java

Lines 25 to 27 in d8e237c

	protected final boolean shouldCheck(@NotNull PsiElement psiElement) {
	return getFacet(psiElement) != null;
	}

As a new Jelly language is introduced with #102, I think Facet will be useless afterwards.
