I can't comment on the effect of the table size restrictions, but in the past I have been very much able to find pick-up games. In theory you should be able to get some of the newly available "drop in" spots, but in practice it may end up being a chaotic mess.
I much prefer structured signups. It's stressful having to worry about whether you'll be the right level for your Monday game.
Ad-hoc organizing seems to happen on these boards and the Warhorn site (which is yet to be updated for this year).
