I'd doubt it. What's far more likely (and probably more useful) is for
the end-date to be one of the inputs to maplint (or other future
tools) to flag things for mappers to double-check at the appropriate
time.

There's going to be so, so many applications using OSM data in a few
months from now, and many will have naive implementations, at least to
start. end_date and start_date is about the 85th thing you'd implement
in a renderer, not the second (behind rendering highways). So it's
probably better to rely more on the community than the technology, as
we usually do.

Again, it's only a hack to make the simple, most common use of OSM
data a little bit easier. We don't want to put off application
developers at the very first hurdle - and it's much easier to filter
by tags than by dates*

Cheers,
Andy

talked about it.
