Just to rephrase that slightly ...

In the above, any clients which are not a member of foo or bar will 
get an address from the first pool - whether they have a host 
statement or not.

So if all configured clients are in foo or bar, then only 
'unconfigured' clients will get an address in the first pool without 
using host statements at all. If 'unconfigured' is the same as 
'unknown' for your purposes then you don't need any host statements 
at all.
