I think, however, that this will be less dramatic than other

it *will* do is make sure that all the old hardware out there that
runs BGP won't work anymore and have to be updated. This is arguably a
good thing. Also remember that this is still some time away. Getting
ever closer, but still a future event.
Given the presentation at the last NANOG, the "old" routers running
16-bit code / hardware / ASICs can just keep going for a very long time.

Or did I miss some important point?

not at all - you are correct. The presentation at the last NANOG said that if you are in a routing domain with an existing 2 byte AS number then you need to change _nothing_. Of course, after a few years, you may come to the conclusion that AS23456 has launched a nefarious plot and is popping up all over the routing world, but you will still need to change _nothing_.
