Following up on this, thanks to Chris we have fast artifact builds for PGO, so the time to develop and use try server is in parity with current opt solutions for many cases (front end development, most bisection cases).
Even as someone not making frequent changes to compiled code I occasionally want to both rebuild and run tests on opt (e.g. because some test changes also require changes to moz.build files that could break the build in a way that isn't caught by an artifact build). In this case adding an extra hour of end-to-end time on try is a pretty serious regression.
For my specific use case it might be enough if we could schedule artifact builds for PGO and full builds for debug. But I suspect it's going to work better for more people — and save more resources overall — to simply keep the default try configuration as-is and just turn off non-PGO opt builds (or at least tests) on integration branches / central.
