IsTrimmable metadata requirement is not flexible enough

We need to simplify how any of our SDKs can be enabled for true (aggressive) linking and ideally the same approach could be used for component vendors or any other NuGet packages. Nowadays this process is controlled using IsTrimmable metadata but there is no easy way to set this within NuGet package or runtime-pack and it can be set only at consuming side.

We could also redo this very restrictive setup and consider making any assembly illinker compatible when it has a certain assembly-level attribute (e.g. ILLinkCompatibility ("link"). This attribute could even be automatically generated by our tooling as part of the build when linker does not report any warnings.

Support IsTrimmable on nuget packages

I don’t think that’s the same thing. Doing manual edits in projects and set IsTrimmable to true for NuGets which are linker friendly is not great.

I think we should discuss it at mono/linker#1194 or open a new issue if they are sufficiently different.

I think that’s a very different concept and will open another issue then

How do we want to prioritize the rest?

#12035 is required and we also need a solution for component vendors to make their NuGets to be automatically linked which I think is the second large missing piece today

I will close this for now - we can discuss in the linked issues, or re-open if there are more missing pieces.
