AFAIK it's generally good to avoid adding more buffer-local variables, 
as their presence has a performance penalty in general.

Updating a buffer list buffer automatically could be done by hooking 
into the machinery that renders a single EWW buffer and having it update 
a buffer list buffer if one exists.  But I guess that wouldn't work 
exactly like `auto-revert-mode` and `buffer-stale-function`.

Another option could be to use a special, non-buffer-local variable to 
store 1) a timestamp of the last time any EWW buffer was updated, then 
update that timestamp in an EWW post-render hook (haven't looked for 
appropriate one), and 2) the time that the list buffer was last updated 
(in the same variable, using e.g. an alist), and compare the timestamps 
in the buffer-stale-function.

I don't mean to say what you should do; just throwing out some ideas.  :)
