To assess the impact of doing this, we will be performing an experiment the week of August 25, in which we will run debug tests on mozilla-inbound on most desktop platforms every other run, instead of every run as we do now. Debug tests on linux64 will continue to run every time. Non-desktop platforms and trees other than mozilla-inbound will not be affected.
To clarify, is fx-team affected by this change? I ask because you mention "desktop" and that is where the desktop front-end team does landings. I suspect fx-team landings are less likely to hit debug-only issues than mozilla-inbound as fx-team has much fewer C++ changes and anecdotally JS-only changes seem to trigger debug-only failures less often.
This approach is based on the premise that the number of debug-only platform-specific failures on desktop is low enough to be manageable, and that the extra burden this imposes on the sheriffs will be small enough compared to the improvement in test slave metrics to justify the cost.
FWIW, I think fx-team is more desktop-specific (although Android front-end stuff also lands there and I'm not familiar with that).
