In the embedded space it's much more common to track -next as people are
often working with multiple subsystems so the integration is important.
Most of my code is developed against -next then moved to topic branches
for submission.
We also catch quite a lot of issues in -next as a result of the work on
boot testing that kernelci.org and Olof's bots are doing, hopefully
that'll start to build out to include test suites like kselftest (I know
there's work in progress there but no ETA as of yet). Things get
exposed to a lot more systems and configurations than individual
maintainers have access to which can shake out issues in code that deals
with hardware.

I think you're mostly agreeing with each other here (or at least talking
about the definition of "mostly") - it's not an either/or thing.
Exposure in -next does expand the audience and provide a lot of risk
mitigation to what gets sent to Linus' tree as a result of that. That
catches more than just integration issues between different trees, it
also catches integration issues with a wider range of hardware and
usage. Not as wide as you see for Linus' tree but wider.
