ITAL feature?

I have a few swash italic glyphs in my latin typeface (E.swsh, J.swsh, etc.), and the automatic feature generation correctly generates a SWSH feature.
But auto features also builds an identical ITAL feature with these glyph substitutions. Is it supposed to do that?

Must be new then. Here’s info about the ital feature:
If you feel it doesn’t apply in your case, simply delete the feature.

This is actually a bug. Fixed it.
