I think a CLA for contributions that pose a high level of risk are a
good idea. I have never stated they are required for all
contributions.

There is no need to require users to sign CLAs because they have to
agree to the terms of the licence to use it this is explicit (although
in some jurisdictions this is questionable, but that is off topic).
There is no equivalent explicit agreement between contributors and the
project unless a CLA is in place.

Mozilla has a CLA [1],  Linux has a CLA [2[, I don't know about KDE

Please let me say again (you snipped it from my reply):

"Just in case my message is getting
lost in the detail, I'm not insisting that all contributions must
carry a CLA. I'm merely saying we need to understand the risks, all
the risks, so that we can evaluate them on a case by case basis."

In other words I'm not saying your opinion is wrong. it is a different
opinion from others, but that does not mean it is wrong. However,
understanding why there are differences should be valuable in a group
called "Teaching Open Source".
