vgo does have that too: vgo get -u
vgo does have that too: vgo get -u
Why would you want to pull a version that is newer than the author of the library you depend on has actually tested with? You can of course force this in vgo, but having the default use the versions specified by the authors makes a whole lot more sense than just using the newest.
1. To install a security update or bug fix update you need in a transitive dependency that the author of the dependency you're using hasn't updated to.
2. To use the same workflows across all my dependency management tools (npm, cargo, composer, bundler, and the rest of the lot follow the same patters and vgo goes against the patterns used by the others)
There are two reasons.
2) seems like a bit of a silly reason, if we all wanted to make everything work the same all the time we wouldn't make much progress or try anything new. Whether vgo's approach is correct or not we don't know yet, but saying that it isn't familiar isn't a good enough reason to not try it out.
To me, vgo matches what we already do in our python projects with a lot of dependencies. Pin everything in a freeze and upgrade on a schedule when we need to. We have seen far too many failures doing it any other way. (IE, using the "latest" of everything, which often either breaks semantic versioning and actually breaks or has subtle bugs that didn't exist before)

The indirect dependency (rsc.io/sampler - which is a dependency of rsc.io/quote), is also upgraded to the latest version v1.99.99 when vgo get -u is done.
