Input device activity tracking is a very good point to raise. Peter once mentioned me that event masking is a thing with evdev nowadays. Even with file descriptor passing of evdev devices, I suppose the compositor could keep copies open for itself, and subscribe only some of the events. It would also be necessary for "system attention" buttons (e.g. the PS button on PS3 controllers) if the kernel does not expose a separate device. Obviously it's a trade-off between the compositor listening vs. not, but I believe both ways are possible even with file descriptor passing. At least the compositor does not need to forward events even if it does listen. > P.S.

You could subscribe and disable email delivery in the mailman settings web page, that should allow you to post without getting the list mail, I believe. Thanks, pq
