Another thing too is that if your main application artifact can be static while your sidecar can react to configuration changes/patches/vulns/updates. Depending on your architecture it can make some components last for years without a change even though the sidecar/surrounding configuration is doing all sorts of stuff. Back when more people ran Java environments there were all sorts of settings you can do with just the JVM without the bytecode moving for how JCE worked which was extraordinarily helpful.

It depends on your environment and architecture combined with how fast you can move especially with third party components. Having the microservice be 'dumb' can save everything.
