The "process swap on navigation" experimental feature on macOS Mojave does not work due to missing browser changes, resulting in frequent load hangs. When enabling the experimental feature in WebKit ToT or Safari Technology Preview for testing, it enables it as well for Mojave's system Safari which is annoying.
I propose we rename the experimental feature so that the feature stays disabled in Mojave's system Safari even when enabled in WebKit ToT / STP.
