Ok, well then maybe I misunderstood what you originally asked for
because I don't see how you can change a fixed allocation to a dynamic
one without touching the driver code which needs to know the major that
was assigned in the end.

Sure. However, is a config option really necessary here? As is, the
extended dynamic region will only be used if there are too many chardev
majors and it shouldn't have _any_ effect on users that have a small
number. So it seems like not selecting that option is just telling the
kernel to be broken for no obvious trade-off.
