Warforged were the only ones I imported into my homebrew setting. They were super easy, just making them be created by the combined efforts of a gnome subrace and a dwarf subrace of my setting.
Shifters as-is wouldn't work in my setting, as the default werecreatures don't exist. I have other types of werecreatures, but I don't have the desire to try and make their shifter version.
Changelings I haven't imported, as I can't find a justification for them to exist in a world without humans, and having another "template race" included with the ones I already have (aasimar, tiefling, genasi are their own race technically, but they can look like any other race only with celestial, fiendish, or elemental embellishments).
Kalashtar never interested me even back when Eberron first released
