Actually it doesn't make sense to do it halfway (for example, why would you 
keep the v2 protocol in the database if it is not supported anymore by 
clients?!).
Either you drop v2 support or you don't, if the community is keen on 
preserving compatibility between "any" client and "any" database. I for one 
am not keen on that. Just as I would drop support for Java older than 1.4 in 
the JDBC driver.

Anyway, the decision is not mine.
