Interesting, this seems to be the opposite of the intention of the
change that caused it, which tried to let you disable the algorithms
without selecting CONFIG_EXPERT. For some reason that is impossible
to know now, they already defaulted to 'n' when EXPERT was set, but
now they default to 'y'.

Does this indeed cause the entire change in size?
