The pyatspi README [1] says
"For new applications, it is recommended to use the libatspi
gobject-introspection binding directly, rather than using pyatspi.
Going forward, pyatspi is unlikely to be actively maintained aside
from fixing bugs."

The replacement is at-spi2-core

Since pyatspi is almost unmaintained, we should consider removing it
from Debian. However, there are still things using it so I'll file
blocking bugs for those packages.
