If its not merged in master, it is fine to merge to experimental.

If a patch lands in 'master' branch, I don't think there is any need to
send it to 'experimental'. The idea of 'experimental' branch is to push
features/changes which are not having enough confidence to make it to
master branch, and get it tested in regression suite over time.

If its not merged, send it to experimental branch, get it merged, and if
there is anything extra needs to be done, work on it, and once stable, send
the aggregated patch to 'master' branch.

'master' branch rebase to experimental will be done once in 6 months,
officially. I will try rebasing once a month, and see if there are no
conflicts, I will force push the branch, but for now, thinking of 6 months
frequency. There has been suggestion to keep it 3 months window (similar to
that of release branch cut-off). Yet to finalize on that.

Assuming it is 'who' and not 'how', Currently I (@amarts) have the
permission to merge patches.
