Yeah, I don't see them as conflicting. I think Lennart's objection was primarily down to the idea that this patch helps desktop users. The majority of desktop users never run anything tied to a TTY, so it's not a win there - it just helps the fairly niche crowd that use the desktop while simultaneously launching heavy jobs from terminals.
...which isn't inherently a bad thing. The people that do do that kind of thing are the people that are more likely to update their kernel more often than their userspace, and they're also the kind of enthusiast population that test kernels early and often and let us know when things have broken. There's obvious benefits in catering to them, but we shouldn't lose sight of the fact that there's way more people using Linux as something to run a web browser and a music player than there are people who ever launch a terminal.
