We just merged a patch series that was first sent in 2013. Some things
take time to get right.

Fetching tracing scripts, plugins or other instrumentation scripts can
be considered a 'security breach' as well. Fetching external tables
(or network access to begin with) can be considered a 'security
breach' as well, depending on how restricted an environment is.
But we don't design our code based on the most restrictive
environments that are hostile to open source concepts!
Unfortunate users that are not allowed to update open source code that
they are using should probably not update it. The other 99.9% of perf
users would benefit from a properly done upgrading/updating feature.
Please stop thinking in terms of restricted, closed environments.
Packaged perf will still work fine for them, and changes will still
trickle down to them.
Thanks,
Ingo
