Yes.

Yes if the local administrator decide.  But you shoud not do this as
package.

Not really to me.  This is getting too complicated and there are cases
people can be surprized.  Instead of arguing over im-switch, What should
happen is redesign of scim for simplicity with redesigned im-switch.

(You can do the same with current im-switch but it will be more mess)

I am thinking along:

= SCIM =
1. /etc/defaults/scim should store few variables
   IMMODE=XIM|IMMODULE
   SCIM=ACTIVE|INACTIVE
2. im-switch place similar hook script to X.
3. The hook script checks alternative system and if it finds scim is
   current choice, it start /usr/share/scim/hook.
4. /usr/share/scim/hook is executed:
   If SCIM is ACTIVE, execute really hook script contents.
     First, check ~/.scim -> if exist execute it.
     Second, check IMMODE, and execute accordingly.

= debconf of scim in postinst =
All question should honor current /etc/defaults/scim is default
1. low priority for SCIM variable : debconf defualt = ACTIVE
2. low priority for IMMODE variable : debconf defualt = XIM
   (if invoked, it should tell negatives of immodule in general with C++
   issues etc while telling good things for scim-kmfl-imengine.)
3. locale in /etc/scim/global value for /SupportedUnicodeLocales: 
   debconf defualt = en_US.UTF-8
   (high priority if locale is not in en_US.UTF-8 nor (one of CJK).UTF-8
   and ACTIVE, otherwise low priority)

= debconf of scim-kmfl-imengine in postinst =
1. In postinst, if it finds SCIM not to be set for IMMODULE in 
   /etc/defaults/scim, ask question using the template from scim as high
   priority.

I did not know it.

I recommend not to do anything in postinst.  Just write README.Debian
and explain how admin should configure SCIM.

Yes.
