Any thoughts about compiler package manager for web assembly?

I am sure this has been thought of, but I haven't found this idea in google
searches.

What would be interesting, is if the web assembly infrastructure/standard
provide some mechanism for automatically dealing with
compilers/interpreters besides javascript.

So much like having a package manager automatically download dependencies
in linux. What may be useful is if there is a online repository of wasm
binaries of interpreters and compilers for all the major languages in the
web.

What this would allow, is for users to insert source code into their
website besides javascript, take for instance those who want to give dart
programming language a shot. The major issues hampering experimentation
with languages besides javascript is the lack of support of browsers for
other languages.

WASM helps solve the javascript hold over client side scripting, but at a
potential cost to openness of the code. Hosting a common popular compiler
infrastructure manager would encourage users to insert normal source code
into their website besides javascript.

Well that's my 5cents to the discussion. I'm sure this is not the only way
to approach the aspect of making wasm more open to others that chose to be
open.

Cheers,
