...other than that the list might indeed get shorter -- only after processing all the server pings.
More convenient for some, that would be -- as you&I&everybody was always only able to sort the list by _the one_ parameter that was most-interesting to the respective user.
On the other hand it would likely spoil the ease of use as well as the simple and direct approach of the lfs user interface by arranging the search-items in a certain hierarchy that must either be known in advance ( like with many counter-strike players ) or easily comprehensible in a self-explanationary way. A huge challenge each time one changes something (or indeed anything -- even small touches ) in that regard.
Keep in mind that not all lfs-players are die-hard all-s(p)orts-gamers and might not even have a clue about the e.g. not-so-comprehensible counter-strike interface. After all, we want to focus on racing, won't we?
(please note that I didn't yet try any of the recent (2 weeks and newer) patches as of yet. I'm still on vacation, kind-of)
