Could you contrast the behavior of this new code with the one we get
from `message--name-table` (i.e. when setting
`message-expand-name-standard-ui`)?

Looking at the code in message.el it seems it should provide a fairly
similar behavior.  It seems to do similar caching, uses
(eudc-query-with-words (split-string orig-string "[ \t]+")) like your
code, tho your code passes an extra t arg to "try-all-servers".
Maybe message.el should also use that?

Any other difference?
