concurring with Simon, following this description, I also do not understand
what this concept of merge trains improves as long as it is not automated
(and we have lots of build power to subsequently build several combinations
of branches).

Once the first branch is good, why not simply merge it to master and then
rebase the second branch on master and test it, instead of postponing the
merge? After all, building is costly, not merging.

Notice that with QA, the concept is that the packages will be available
on the build farm once the branch has been built, so postponing a merge
has no advantage.

Andreas
