I would very much suggest doing so, yeah. Having timestamps for
high-frequency/resolution mice seems like a real need. Given the need
to correllate the event streams (e.g. 'is someone holding down Ctrl
whilst I scroll?'), it makes it easier for clients if we have
comparable timestamps between the two.
