I think the documentation answers that part pretty well:

  "The driver is allowed to advertise a theoretical limit that it can
   reach in some cases, but may not always reach."

So I still thank having the drivers to advertise the theoretical maximum
numbers of client is useful, even if it would not be always 100%
correct. For example, an average user most likely will not have any clue
if the limit is 10, 50 or 100 clients. And besides, very few people use
P2P anyway ;)

But of course this is just nice-to-have category cand we have far more
important things to fix first.
