I'm really just stating the reality here. We strongly prefer landing
patches upstream over doing custom hacks, and depending on the
priority of a given feature/sub-system and impact on schedule we can
allocate more time on it or less. In some cases/at some point a
downstream patch is just good enough.

I definitely don't intend to get a patchset landed if it isn't deemed
ready or suitable at all. In this case I just can't justify to spend
significantly more time on it. IMO it is better to be clear on this,
not to pressure maintainers to take a patch, but so people know what
to expect. This information can also help if someone comes across this
patchset in the future and wonders about its status.

btw, a birdie told me there will be a talk next week at ELC in San
Diego on how Chrome OS works with upstream, discussing pros and
cons for both the project and upstream. For those who are intersted
in the topic but can't make it to the conference, the slides are
already online and IMO have good information:
