Ideally, there would be some kind of prompt or reminder: you recently
tagged a node with shop=antiques; if this was intentional, please go
to whatever/tags/shop and add the new value with a description.

Or, you recently tagged a node with shop=literature, but the database
(visible at whatever/tags/shop/literature) suggests that this is
deprecated in favour of shop=bookshop.  Perhaps you would like to change it?
