But this is part of the ABI to userland.  You cannot remove sysctl files
without long advance notice documented in feature-removal-schedule.txt
(if at all).

If it is possible to add the paths
/proc/sys/net/{tcp,udp} while retaining aliases under /proc/sys/net/ipv4
then that might be a workable solution.
