[Q] Hebrew Keyboard Android 4.4.2 & 5.0.0 topic

Hi everyone :)
I'm opening this post because i would like your help to understand once and for all the subject of HEBREW in Android Lollipop and KitKat.

I have a few LG G3 D855 Phones (Ver 10O & 20F Stock ROM).
Some ISR (Israel) Model, Some EUR, SEA, TWN etc...
The G3 ISR model have Hebrew keyboard and all the menus can also be in Hebrew if users want to.
But the EUR\SEA\AME\TWN models can't add Hebrew Keyboard from the STOCK ROM KEYBOARD LIST.

I installed MoreLocale2 and PM the SEA, EUR, TWN Models. the GUI changed to Hebrew and the entire device is in Hebrew.
BUT, users still cant add HEBREW KEYBOARD from the keyboard list. so they can't type in Hebrew.

Can someone explain to me why users cant add Hebrew to the keyboard list?
how come all the menus in the phone are in Hebrew but you cant type in Hebrew?

I can solve it by installing any keyboard from "Google Play" that support Hebrew (Go Keyboard, AI Type etc...) but i don't want to do that.
is there anyway to add just HEBREW KEYBOARD to the list?

- Can i extract it from the ISR (Israel) ROM and install it on G3 EUR\SEA\TWN Phones like .APK file?
- If i'll install the ISR ROM on the EUR device and PM the device after morelocale2 will it have Hebrew keyboard then?
- Google press release docs says that since Android 4.3 HBEREW is built in inside Android so why is the keyboard missing?

Thank you.
