Yes, it's likely a better way to go.
It can be pretty simple, even a shell script.

The xim.d mechanism can (should) be still used to set the initial
environment variables or starting a daemon that doesn't need the
upper layer.  The xim.d script can set a certain env variable, e.g.
$USED_INPUT_METHOD, when the IM is chosen and set up.  It will contain
the IM name such as "ibus" or "scim-bridge".  Then the launcher
invokes another program according to this variable, when necessary.

For example, create a script /etc/X11/xim.d/uim-launcher, which starts
the systray stuff.  Then the generic launcher would execute it
like:

	#!/bin/sh
	test -z "$USED_INPUT_METHOD" && exit 0
	test -x /etc/X11/xim.d/${USED_INPUT_METHOD}-launcher && \
		exec /etc/X11/xim.d/${USED_INPUT_METHOD}-launcher
	exit 0

and put a desktopfile in XDG-compliant autostart path.

Hopefully this can be resolved, too.
