#80896 (comment)

SR.GetResourceString is not getting inlined because the original method body was pretty big. What we're left with after rewriting is just a simple mov rcx, rax.

We'd need to basically redo how substitutions are processed.

I'm putting this in the future milestone. Ideally we should not have this code - we should use RyuJIT to do IL scanning and introduce ability to feed it substitutions. RyuJIT is much better at constant propagation than anything we would write in C#. No point maintaining two codebases. Just filing this for tracking.
