Bug Description
Legacy BSD PTYs have been replaced by UNIX 98 PTYs a long time ago. Disable legacy BSD PTY support as it is no longer needed.
This config option is recommended by the Kernel Self Protection Project[1] and a 2019 study performed by Capsule 8 shows that it is enabled in some other major distro kernels[2].

This change was applied during the Focal development cycle but then reverted pending performance testing results. That performance testing work was never finished and I'm no longer working on this bug.
