Thanks, that confirms and details their availability as public suffixes.

These suffixes were specifically provisioned (and are not themselves
delegated, they are included directly in the .in zone) by the .IN ccTLD,
and I am curious whether the intent was specifically to "mirror"
similarly named ccTLDs (and if so, why), or whether perhaps these
2-letter abbreviations have some other significance in India...
