Good work, Arjuna. (Though not a fan of phonetic keyboards that rely on English alphabet sounds due to long term negative impact,)
 I agree. May be some people are comfortable with that.  We have to wait for Google  to   provide  inscript keyboards for other languages or make  inscript/alphabetic keyboards ourselves.
I tried Tamil and Malayalam and they both work very well. One suggestion would be to handle backspace to erase the original input. For example, if I've typed aa in Malayalam, and press backspace, it should retain 'a', no?
The backspace works on the converted unicode characters.
If you type ra,  backspace will delete the whole unicode letter. If you type raa  to reflect long  vowel, one backspace will  make it equivalent to ra.

If you are starting the word with aa, it becomes  a single unicode  character corresponding to long  vowel (A).
