I see that an entire discussion has taken place. Let me just remark this,
quoting the Austin draft:

If the path argument refers to a path whose final component is either
dot or dot-dot, rmdir( ) shall fail.

EINVAL The path argument contains a last component that is dot.
EEXIST or ENOTEMPTY The path argument names a directory that is not an empty directory,
EBUSY The directory to be removed is currently in use by the system or some process
and the implementation considers this to be an error.

So, it seems that -EINVAL would be a better return value in case LAST_DOT.
