This made me wonder, why not have functionality in Gnus that
"gathers" all the group/topic parameters into the gnus-parameters
variable, and then the opposite functionality, that would take
gnus-parameters and apply its values to all the known groups,
whenever they apply?

Would this be useful to anyone?  I would love it, because then I would
set group/topic parameters individually with `G p', and then one
command would gather all my customizations into gnus-parameters.
