I don't think so. There's a fair number of algorithms that can/could be much easier be attached with lots of data available. Especially if you can guess/know/control some of the data. Additionally renegotiating regularly helps to constrain a possible key leagage to a certain amount of time. With backend connections often being alive for weeks at a time that's not a bad thing. And it's not just us. E.g. openssh also triggers renegotiations based on the amount of data sent.
