Yes. But we're right now in the territory of baby steps, so that when we
get there we can be confident that we only make new and interesting
mistakes :)

In particular, I hope to have stuff that is experimental and introductory.

And as a general background, we need things that are easy enough that
people don't get them wrong, otherwise the data becomes useless. The
approach is very much geared to "find a place that is OK for *me*" rather
than "find a place that did a good job meeting accessibility requirements
in general".

My first thinking was to have "x-wheelchairFriendlyNotes" and
"x-problemsForWheelchairs". The idea is that the former is likely to be
filled in by the people who are promoting a venue, pointing out all the
good things they have done, and the latter by people reviewing, who might
have a different experience.

The thinking is that this will help us get a sense of what people are
prepared to describe in practice, as well as some sense of how to handle
granularity - for example many bars in Madrid have zero to two steps,
which makes them accessible to some wheelchair users in some situations.
They often have the toilet downstairs, which again is useful information.
As bad as it is in a general sense, not everybody actually uses the toilet
in a bar.

But that got some pushback. An alternative proposal was "can a wheelchair
get into the front door?" Which I would be OK with except that it wasn't
set up as something we could use and I didn't follow it up.
