There are `GraphDSL.create` overloads that take up to 22 input graphs and allows to combine their materialized values.

There's a PR in progress working on a version that accepts a list of graphs: #24102

@sebastian-alfers it is better to rebase rather than merge master, since it allows us to do a single squashed commit when PR is done. If you can drop the merge...

Aha, it actually does need some MiMa excludes for those new methods

@He-Pin any chance you'll have time to continue this PR any time soon?

I think a complete-after-idle would be nice. Not sure I think the transform-failure-to-completion one is a good idea since I think that having that may make people think ordering is...

I think you could rather describe it as: 1. stage fails 2. in some order * upstream is cancelled * failure is propagated downstream.

Trying to re-trigger validation

Yeah, sorry to leave this hanging, would be good with another opinion, @jrudolph or @raboof ?

Sorry about the long wait, busy days and vacation times so will likely be a while more before any additional feedback.
