ossification is a stupid weasel word anyway
you don't change something that works
you change something that doesn't work
improvements have to be weighed up against how they will be used, the block size is a good example of a case where in some measures it's an improvement but in others it is a major problem
so, please, stop talking about ossification as though it's always a bad thing to never change things
we still mostly use programming languages with braces around function parameters and parentheses around code blocks, and hell, how many thousand years have we been using arabic numbers?
omg, arabic numbers are so ossified, we should invent some new shit for no reason
