 ## Criteria to add to defaults
 
 Suggestions for adding to the defaults are welcome, but good evidence is
 needed that they are common typos.
 
+Short words are preferable to long words to avoid the list becoming too
+large and slow to load.

+Note that existing `iabbrev`s may be removed to make way for new ones, to
+keep within the stated limit.
