You already have that pipeline for release/deployment though, don't you? (And it's already hooked up to your SSO or what have you).

It's the same as any other library dependency though, which is a completely normal thing to deal with. The cost of separating your pieces enough that you can use different versions of a library in different services is that you can use different versions of a library in different services.
I'm skeptical about microservices as a deployment model, but I'm absolutely convinced that code-level modularisation and independent release cycles for things that deploy independently are worthwhile, at least if your language ecosystem has decent dependency management.
