Why would you suddenly be calling @system functions from @safe code?

If all functions in your call chain are currently not marked, then you 
mark them all as @system for the DIP, and the code compiles just as it 
used to.

If the calling function is currently marked as @safe but the called 
function isn't, then the chain already doesn't compile.

Yes. And if you want your working unsafe program back, you have to add 
lots of @system attributes.

You might oppose the DIP on the grounds that that's too much hassle for 
too little gain. That's a reasonable position.

Treating all legacy code as @trusted (when it was clearly @system 
before) would not be reasonable, in my opinion.

All that said, you *can* slap `@trusted:` onto your modules, of course. 
You really shouldn't, but you can.
