Comment:

 I had a list of 13 taxonomies to register for certain CPT. Of course, I
 knew about reserved terms, but It didn't occur to me to check and as the
 result I registered "themes" taxonomy. It worked fine, but I got a side
 effect that was difficult to discover as editors were using Thumbnail
 block to add Thumbnail and no one was complaining that "Set featured
 image" button is gone.

 I think _doing_it_wrong() will be very useful to notify that word is
 reserved and cannot be used as taxonomy.
