I don't think I've had the need for a uniformly tagged array of enums. Generally, when I do an AoS to SoA transform that includes tagged data, I just factor out the tag into its own array. In fact, if the tag is 2-valued, I just build a bitmap, rather than burning a whole byte. If the tag is a resource indicator, then I have a group of 1-hot bitmaps.
