JSON Home is on our list of things to do for the API (but
the priority is lower than microversions). We still need
microversions anyway because we want to be able to support multiple
versions of API through the same resources (ie no url changes). To
make life as easy as possible for users so they are not forced to
upgrade their app whenever we make backwards incompatible changes. I
don't see us supporting every version forever, but it gives them some
time to upgrade.
