[orca-list] Proposal: Nuke the forced terminal-based setup

[Joanmarie Diggs <jdiggs igalia com>]

Hey guys.

I have a new proposal for you. As the subject indicates, I am thinking
that the forced terminal-based setup needs to go. Here's why:

1. If Orca is started via GNOME's built-in universal access tools,
   the autostart file we were provided (and are expected by GNOME to
   use) prevents the terminal setup from ever kicking in. So in this
   case forced setup is useless as a result of going unused.

2. If Orca is stopped via GNOME's built-in universal access tools
   and then launched manually, terminal setup kicks in -- which is
   not desirable. For one thing, accessibility support for the desktop
   session is still enabled functionally. But the gsettings key says it
   is no longer enabled. So we don't actually *need* to enter setup.
   Furthermore, if you go through with it, the setup stomps on your
   existing settings. So in this case, it's at best silly and at worst
   causes you to lose preferences.

3. If you always start Orca manually and you are in an instance where
   accessibility support is really not enabled, forced setup simplifies
   things for you. However, it assumes that you have gsettings -- that
   won't be the case for pure KDE and pure XFCE environments. And for
   that matter for any other pure, GNOME-free environments. The 
   gsettings thing we can deal with via using dbus instead (which is 
   what I'm working on now for some other stuff in Orca), but:

4. If Orca determines accessibility support is not enabled and does the
   forced setup, it does it by launching (or attempting to launch)
   gnome-terminal -- which won't be installed in pure non-gnome 
   environments. So I suppose we could try to figure out from the 
   environment what the native terminal is, but.... This really should
   be a one time thing -- and ultimately a no-time thing because:

5. At the last Accessibility hackfest, we discussed and made a high 
   priority getting accessibility enabled by default. As things continue
   to get more performant and more reliable, we can do this. We're
   aiming for GNOME 3.6. With accessibility support always enabled,
   forced setup will never, ever be invoked. And lastly:

6. For the one time it is truly needed, you can always use 'orca -t'
   in a console.

So.... Personally I think this code is more trouble than it is worth.
What are your thoughts on this matter? Discussion and +1/-1 are highly
encouraged.

Thanks in advance!
