which, from a repo standpoint, is very hard to award. Why should
joebloggs repo be a higher score than janebloggs? Do you trust joebloggs
more than janebloggs? And if so, why do you have janebloggs  enabled at
all?

As many times as I've tried to explain it it's amazing how many people
don't understand it. Sensible defaults w/o hundreds of knobs to push is
how you make software that dtrt. If you focus on making it for the
extremely complex case you end up with a program that's hard to program
for (b/c of all the if statements) and difficult to design a workable ui
for.

But think about if you got in a car with hundreds of dials all over the
dashboard. Hundreds of them. How would you know which one to touch, or
worse yet, not touch.



the repo scoring implementation code-wise is not all that hard - you
just add an attribute to the repository object and you use that as your
first-order separation when you have two packages of the same name from
different repositories providing the same requirement.

Of course this doesn't even get into how you deal with obsoletes. Can a
package from a score 0 repo obsolete a score 2?
