Yes;  

I got the impression that it would have been possible to use the .NET
Symbol Writer interface with a few hacks in mcs. 

If I remember correctly, and this is a very blurry topic to me, we were
missing a way of activating the symbol writer, or we could not figure it
out a few years ago, so we came up with this.

But nowadays I get the impression (maybe someone proposed a patch, or
there are other reference compilers that do this) that it is possible to
do this with pure managed code.

On Mono we could just hook the Mono SymbolWriter behind the official
API, but as I said, this is a very blurry topic to me, I do not remember
the details, its been at least two years since I looked at this.
