Fedora 34 Change: Use ibus-m17n as the default IME for Sinhala (System-Wide Change proposal)

https://fedoraproject.org/wiki/Changes/ibus-m17n_as_default_Sinhala_IME

== Summary ==
The current default input method for Sinhala is ibus-sayura. This
should change to the ibus-m17n input method "m17n:si:sayura - sayura
(m17n)"

== Owner ==
* Name: [[User:Mfabian| Mike Fabian]]
* Email: <mfabian@redhat.com>


== Detailed Description ==
The current Fedora default input method ibus-sayura seems to be not
actively maintained.
Fixing bugs like this one

https://bugzilla.redhat.com/show_bug.cgi?id=1724759

is therefore difficult.

The ibus-m17n input method si-sayura.mim does exactly the same (I
developed this one to be an exact replacement for ibus-sayura).

As ibus-sayura offers no additional benefit, it is probably better to
use ibus-m17n with si-sayura as the default input method for Sinhala.
ibus-m17n has to be maintained anyway. Therefore, this saves the
effort of fixing the unmaintained ibus-sayura.


== Benefit to Fedora ==
Save maintenance cost in maintaining ibus-sayura. si-sayura from
m17n-db can be used both with ibus-m17n and with ibus-typing-booster,
so actually it is more useful than ibus-sayura.

== Scope ==
* Proposal owners:
** update default IME in comps @input methods
** update langpacks-vi to use ibus-m17n and m17n-db
** the langtable package has data about default input methods. Change this data.

* Other developers: gnome-desktop3 for default si_LK input method
* Policies and guidelines: N/A (not a System Wide Change)
* Trademark approval: N/A (not needed for this Change)
* Alignment with Objectives:


== Upgrade/compatibility impact ==
The package installed by default will change from ibus-sayura to the
packages ibus-m17n and m17n-db for an installation in Sinhala.

== How To Test ==
Install Fedora in Sinhala and check that the default input method is
si-sayura with ibus-m17n.

== User Experience ==
* There should be very little difference in typing Vietnamese as
ibus-sayura and ibus-m17n with si-sayura.mim behave the same.

* The setup tool looks a little different.

* Package sizes and dependent packages are different.

* Memory usage is different.

== Dependencies ==
ibus-m17n and m17n-db

* comps has to be updated

== Contingency Plan ==
Revert changes back to ibus-sayura

* Contingency mechanism: Revert comps and gnome-desktop3
* Contingency deadline: Beta release
* Blocks release? No
* Blocks product? None
