I totally agree, but it's not clear to me whether continuing to do PGO
on desktop Linux has any effect on our ability to potentially do PGO
on Android/B2G.  If we were to stop doing PGO on desktop Linux
tomorrow, would that make it much harder to do PGO on mobile in the
future?

Our testing of PGO Linux builds may be papering over performance problems that affect non-PGO Linux builds (i.e. B2G, Firefox for Android, and distro-built Linux builds).
