Could you use a compatibility layer? Say you have a module that
is pre safe by default, you could have a component that annotates
it so it's safety is explicit and then it can be passed to the
new safe by default compiler.
Like the error with ints being truncated on assignment (cant
remember what the proper name for it was), you could have a
component that just inserts casts where needed, and then it could
be passed to the newer compiler.
You wouldn't even need compiler versioning, the module could just
declare the specific feature it's not updated to yet, and that
would cause it to be run through the compatibility process.. Eg..
