I'm suggesting the "default mode" would be that updating is explicit rather than automatic.

The "10-15" year old comment can be taken in the context of language specifications for example. C++11 is a totally fine language standard, and since backward compatibility is the only reason for C++ to exist at this point there is no intrinsic benefit in using a later version.

This, I agree with. Though for modern codebases, leveraging tools like Dependabot is very helpful. Deliberate upgrades, with automation to make it practical.
