perhaps the oncall is better if you write your own services, but as an SRE / ops person who has to run other people's services, rust ones just generally seem to be worse: logs that are so verbose but seem to tell you nothing, statsd seems to be the only choice for metrics, contextless errors everywhere, memory "leaks" (more like runaway memory use) that the developers swear are impossible because it's rust, overall just less mature across services written by both in house and oss teams
