Hello @sipaktli, please do not intentionally open duplicate issue reports. You were given a straight answer that there is an alternative available by using a setuid-root variant of bwrap on #11237. If you have further concerns with bwrap, then direct that feedback at the upstream bubblewrap project.
If you want bwrap to work differently on a technical level, then work with that project to meet your needs. Convenience link: https://github.com/containers/bubblewrap
Closing as a duplicate of #11237.
Nothing extracted yet.
Recently you have started to demand the use of unprivileged namespaces (UNs) without providing any technical rationale for it.
You have provided the following link as a justification, but what is says is basically "modern systems use flatpak so it must be cool". That is not a valid technical reason.

The use of UNs leaves the system vulnerable to a plethora of vulnerabilities. The extent of which being so that it does not justify you requirement.
Basically you have gone the nuclear option, and I will assume malicious intent unless you can provide a valid technical justification.ac
