What do you think would be a reasonable largest size multiplier
(as opposed to actual brush size)? The current value is 1000.0 -
in the previous version it was 10.0.Also, up to GIMP 2.6, feaures that
from 0 to 1000.0 (like actual brush radius) would vary in a logarithmic way,
meaning that if you started with a value of 5.0, small variations
close to that would make changes from 2 - to 20.0 --if you started at
the same small variations could take you to 150.0 - 1000.0

Maybe, simply having the  largest brush size as  a value in preferences
could make up
for all use cases.
