I know this was existing behavior, but I find it kind of weird that we are passing in these "untrimmable" assemblies as References for the trimmable assemblies.

@joperezr - do you remember why it was done this way? I would hope we don't have any "trimmable" assemblies that reference these "untrimmable" assemblies... that would seem backwards.

This is what you get when you don't pass them in as references:

I.e. PerformanceCounter relies on ConfigurationManager here:

runtime/src/libraries/System.Diagnostics.PerformanceCounter/src/System/Diagnostics/DiagnosticsConfiguration.cs

Line 69 in f249dc7

bool setConfigurationSystemInProgress = (bool)(typeof(ConfigurationManager).GetProperty("SetConfigurationSystemInProgress", BindingFlags.NonPublic | BindingFlags.Static).GetValue(null));

Runtime.Caching depends on ConfigurationManager as well:

runtime/src/libraries/System.Runtime.Caching/src/System/Runtime/Caching/Configuration/MemoryCacheElement.cs

Line 72 in c9feedf

System.Runtime.Caching also relies on ConfigurationManager:

runtime/src/libraries/System.Runtime.Caching/src/System.Runtime.Caching.csproj

Line 85 in f249dc7

<ProjectReference Include="$(LibrariesProjectRoot)System.Configuration.ConfigurationManager\src\System.Configuration.ConfigurationManager.csproj" />

I verified that ConfigurationManager is the only dependency that needs to be passed in. Should we filter this down and just pass ConfigurationManager in? Of course, ideally we would not have this dependency at all.

Is there an issue that tracks marking these remaining assemblies as trimmable? (if that's even possible)

It is not necessarily wrong for trimmable assembly to depend on non-trimmable assembly. The trimmable assembly may have this dependency just for a small part of its functionality. If your app does not use this small part, it is still going be fine with trimming.

Is there an issue that tracks marking these remaining assemblies as trimmable

No, I would leave it for now.
