 * Achieve good / efficient interoperability between hosts, modules, JavaScript and Web APIs
 * Achieve similar ecosystem benefits in WebAssembly as have languages running on the JVM or CLR
 * Avoid ecosystem fragmentation as would be introduced by separate mechanisms to use on and off the Web
-* Avoid alloc+copy->garbage at the boundary in between two Wasm GC-enabled languages and/or JavaScript
+* Avoid alloc+copy->garbage at the boundary in between two Wasm GC-enabled languages and/or JavaScript (especially if a GC is not or cannot be highly tuned for this case)
 * Avoid code size hits by having to handle strings explicitly at the boundary or shipping basic string functions and their dependencies with each module
 * Avoid hurting developer experience, like having to author, publish, ship and/or install a variety of adapters for/in different use cases
 * Avoid redundant re-encoding overhead when forwarding strings to multiple modules expecting different encodings (think npm)
