Closes #589

LPTM (looks perfect to me)!

(one comment bellow, but probably not something we should worry about)

I was thinking about what if someone imports Patternfly and uses it this way:

import * as PF from '@patternfly/react-core';

<PF.MenuItemAction></PF.MenuItemAction>

I hope nobody does it, I checked the getFromPackage helper and we don't handle this ImportNamespaceSpecifier there either. So if we don't know of any team who would do it, we don't have to worry about it, it would bring too many complications.

Ah that's an interesting point! I don't think we had any consumers bring this to our attention during the v5 release (@wise-king-sullyman do you recall if we did?), but worth keeping an eye out for with v6 alpha and beta releases

That's in the same realm as the root problem behind #541, IMO it is probably worth us properly handling all of those import cases, but I don't think ironing those edge cases out is worth holding up the alpha release of the mods.

I think TS will be a big help with these kinds of problems, typing getFromPackage made it pretty obvious that we aren't logically setup for all of the potential import declarations.
