The problem is that Alexander wants these sysctls to only be temporary.
Recall that big thread from a month or two ago about treating sysctls
as an API, and how there was heavy disagreement over how to define
"stable" sysctls that apps could depend on?  If a temporary set of 
sysctls get put under the dev tree, then it risks becoming permanent,
which is not what Alexander wants.  So, either we need to decide what
parts of the sysctl to define as stable, like I asked for in the 
previous thread, or we need to pretend that it's not a problem that we
should address, and let you and Alexander continue to argue over the
'correct place'.
