Yeah, I don't see any reason to prefer the separate INCSGROUP over LSUBDIRS, this seems sane.

OTOH, we probably just need to add it to this list here and in the symlinks target to limit it to just the one header we need for userladn.

strip dev/wg from LSUBDIRS in the copies and symlinks targets instead

Yes, the intention was to only install the one header needed for userland, not all of them.
