dev-libs/m17n-lib-1.7.0 blocks dev-db/m17n-contrib-1.1.14 (Bug 623974) which is required by app-i18n/ibus-m17n-1.3.4 and causing a hard block.

There are several non-CJK languages (like those using Indic scripts) for which ibus-m17n is the only ibus engine I know of.  For reference, fcitx-m17n does not seem to rely on m17n-contrib.

[blocks B      ] dev-db/m17n-contrib ("dev-db/m17n-contrib" is blocking dev-db/m17n-db-1.7.0)

Total: 5 packages (4 upgrades, 1 new), Size of downloads: 3,470 KiB
Conflict: 1 block (1 unsatisfied)

!!! Multiple package instances within a single package slot have been pulled

It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously.  If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously. You may want to try a larger value of
the --backtrack option, such as --backtrack=30, in order to see if
that will solve this conflict automatically.

page or refer to the Gentoo Handbook.

As far as I can tell, dev-db/m17n-db-1.7.0 seems to effectively include the IMs that were previously in m17n-contrib so it seems that the issue is just one of re-working the app-i18n/ibus-m17n-1.3.4 to not require dev-db/m17n-contrib-1.1.14 if >=dev-db/m17n-db-1.7.0 is installed.

ibus-m17n-1.3.4 without m17n-contrib

I have been testing ibus-m17n with this ebuild having removed the dependency on m17n-contrib and it seems to be working well.  However, I have not rigorously tested using the input methods and only use three out of the several languages provided by the package so my testing is limited.
