This is just a wild guess from my side because I was not involved in this change:
I think there is generally nothing wrong with flex/bison but you would possibly switch to hand-written code to get better performance and to have better control on the code of the lexer/parser (though not depending on externals tools whose generated code might change). By using hand-written code you could then specifically tune some parts of your code.
But maybe, you'll also get an answer from someone being involved in that change ;-)
Best regards,
