You probably missed my point here. I do accept that the secondary language based domain names like in Hindi, Tamil, Malayalam, Telugu, and Georgian are way behind the curve in traffic and revenue when compared to the IDNs in Chinese, Japanese, Arabic and Russian, even if they don't get type-ins as of now.
Unfortunately this scenario doesn't work with languages which are rarely or not at all used in online. Keeping IDN names from such languages, are nothing but waste of time and money even if they contain just a single letter. This is what I was implicitly trying to say in my previous comment.
