I started looking into more after last reply. I think exposing this info can be useful to the operators - dashboard of region states, or tools to quickly dump list of regions which require care, etc But wasn't thinking about hbase rest api so far. I think web ui is not the right endpoint to expose json api when we already have a whole well designed way to do it - REST apis. It should rather be an addition to Table endpoints (table 14 here: http://hbase.apache.org/book.html#_using_rest_endpoints).
