A substring of text may or may not be a date and based on the excellent tools available in linux you can decide how to extract that "data point". If binary logging is little more than a stream of text, then that is fine, but I seriously doubt that is the push happening. Personally I prefer having a raw stream of data that I have to work with as best as I can rather than having to use some flag defined by somebody else to range across dates. That is the fundamental difference it seems: do you want a collection of tools that can be applied in a variety of ways or do you want the "one way" (with potential versioning... have fun!).

Again if the binary log is simply better compressed data, well we have ways of compressing text already as an afterthought. This really, fundamentally, seems to be a conflict in how people want to administer their systems and, for the most part, this seems to be about creating a "tool" that people then have to pay money for to better understand.
