The HN bubble can be amazing sometimes.
The burden of updating multiple copies of the same library across many packages grows exponentially and is simply untenable for distributions.
If you can find an army of volunteers to do that, distributions would love their contributions.
This hasn't happened in the last 20 years. I'd love to be proven wrong.
> If there are no resources to carry that burden, then the only option seems to be to wait for an updated release from the upstream, whenever that arrives.
No, most upstreams do not backport security fixes. And switching to a newer release is not an option if you want to provide stability to users.
now the build tooling still needs some work around versions but its only a minor problem generally as much as it annoys me personally.
