Hmmm
Here's a current draft of what is now the O_NOCMTIME series. It
implements the frequent suggestion to gate unprivileged O_NOCMTIME use
with a mount option.
This method has the advantage of being entirely runtime. There's no
persistence that'd require updating all the tools that deal with each
set.
This requires priviledged intervention to testify that mtime isn't
critical to, say, backup infrastructure or NFS server consistency
guarantees.

Currently the high level vfs entry point limits copy offloading to files
