Application to be comaintainer

Great, I think you can start by going through the RTBC queue and rigorously testing the patches for backwards compatibility. If they pass your check maybe tag them with "cweagans approved" or similar?

Committing the stuff is not the thing which is time consuming, but its rather the possibility to trust the people's RTBCs.
Ideally something like 'cweagans approved' would be indeed great.

So what about getting obvious quickfixes in and move them to Drupal 8, if needed?

As I understand, new Views features aren't really in the cards (so that D8 core and D7 contrib can stay in sync)

Well, as long they are just incremental improvements in some special handler, I think its not a big deal, but keep in mind that solving things in Drupal 8,
might require total different solutions, especially now that #2342045: Standard views base fields need to use same rendering as Field UI fields, for formatting, access checking, and translation consistency is in.

In general we should avoid in any way to break existing sites.

I'd like to be a Views comaintainer, and I have the bandwidth to do it now.

That would be super great!
// No offend @colan if you read this ...
You know, just the other day @colan seemed really open in IRC, but meh, one commit happened, that's it.

Just gave you the needed rights.

(I'm on vacation Saturday-Tuesday).

Good to know.

@dawehner, just to make sure we're on the same page, you want me to commit obvious stuff, open issues against D8 as necessary, and re-review more substantial RTBC patches, right?

That would be great!
