In fact, it is quite obvious where the problems will lie once we
start this conversion: branching ways, and non-contiguous ways.
Both of these can be identified and, mostly, changed to simple
structures *now*, without changing the data model one bit, so that
automatic conversion will be easier once it is attempted.
I am already doing this now; whenever I encounter such ways, I change
them into simple linear structures. I'm also experimenting with a
Perl script to find those cases that cannot be converted
automatically. (Those that are auto-convertable are not too
interesting for now.)
