There was a running joke (out of frustration, really) back when I was at Google (2013) that Hangouts was happily adding hundreds of new emoji, yet did not consider "reliable message delivery" to be a key feature.
Some of this is consumer vs. enterprise tension, though. Emoji demo really well on an initial product tour; reliability is one of those key features that's really hard to get people excited about, but which people hate to find lacking.
