What is the default value of the `access` tag?

The default value of the `oneway` tag on `highway` is `oneway=no`. But I
don't think `access` has a default value *for all OSM objects*. For
`highway=primary`, the default is `access=yes`. For `shop=supermarket`,
the default is `access=permissive`. We don't add `access=yes` to roads,
so we shouldn't add `access=permissive` to supermarkets.

So what's the default `access` for `amenity=place_of_worship`?

I don't think there can be a default *for all types of PoW*.

  * `access=permissive` is the default for Catholic church facilities in
Ireland, but `access=private` for Catholic friaries & monasteries.

  * `access=adherent(s)` for some Muslim facilities in Morocco (right?)

  * `access=permissive` for Mormon genealogy facilities, but
`access=adherent(s)` to the Mormon temple facility (right?)

I think data consumers need to use their heads. If you're making a
cycling routing engine, use a default `bicycle=no` for
`highway=motorway`. If you're making a site to show tourist-y places in
a city, don't include `amenity=place_of_worship` with
`access=adherent(s)/no/private`, and if there's no `access` tag, then
look at the other tags/location and make an educated guess. If you're
making a "Find my local Catholic Church" app, then include
`access=adherents` or a missing `access` tag on a catholic church.
