In our wiki hive states:

Hive does not mandate read or written data be in the "Hive format"---there is 
no such thing. Hive works equally well on Thrift, control delimited, or your 
specialized data formats. Please see File Format and SerDe in the Developer 
Guide for details.

So if the new format does not require large scale changes to accommodate I see 
no issues, and would be +1.
