If it's not possible to use this attribute, should it not be removed from the schema?
No. Others could have defined a custom schema using it. Removing the attribute type description would render their custom schema invalid. In general removing schema descriptions is strongly discouraged.
I wasted quite a lot of time trying to figure out how to use it, only to find out that it's not available.
Determining whether to use standard schema or define custom schema requires some experience. Of course there's a learning curve to take (like with anything else).
