Neutral synths are rare nowadays. It's usually helping survivors and going very aggro on aliens that try to get colonists. Due to this, they built up a reputation of being a very valuable asset to colonists and marines later. Xenos don't want to take a risk leaving a synthvivor alive. Also unfortunately, roleplay between xeno-synths is even rarer, because xenos always have an objective to expand their hive and yeah, as much as I hate to say this, combat > roleplay for significant majority of people.
At the end of the day, synthvivor can be revived pretty much always. Just don't die in some unreachable location.

The few times I farted around as a survivor synth as neutral I've always referred to the xenos as colonists and remind them to watch out for mosquitos on LV or use sunscreen on Big Red, and they've never bothered me.
