core is still winning, by a lot

there is basically no competition
But is this chart really representative? Say if you're in favour of increasing cap to 2mb, you could just change the code in your core client by replacing "1" with "2" in MAX_BLOCK_SIZE line and recompile. I reckon it would be still shown as Core client. Am I right?
It would make no sense to just create a single person patch and hope it works.
The number of classic nodes seem to have hit their maximum for now.
