Well I'm just saying that there was no particular thought in
choosing 2000 in the first place.

For really old devices that have limited memory you may only be able
to load a few tiles at a time and then it would be more flexible to
have smaller tiles.  But this is really from before OSM was started,
I've never had anyone complain that tiles were too big, in fact quite
the opposite.

So ideally you want to be able to make the tiles as large as possible.
However if you only look at the number of nodes then you find that
you have to have it quite low to cope with one particular area
when a higher value would have been fine everywhere else.
