The problem is that there are only very few people who are 
familiar enough with the DMD backend to work on such changes.

And quite understandably so – to be quite honest, I myself am not 
particularly interested in spending a nontrivial amount of time 
to get acquainted with a dated, sparsely documented codebase that 
I will not be able to use in other projects. It certainly is an 
interesting piece of software and getting acquainted with its 
internals is probably a nice intellectual exercise, but so far, 
most people interested in tackling the ABI situation are already 
busy with another backend.

Sure, one way to go about this would be to just sit down and 
implement a common ABI in GDC and LDC (hackathon at 
London/Zürich/… anyone?) and then hope that some random 
contributor turns up later on and fixes DMD to conform to the 
standard we agreed on. But this does not necessarily strike me as 
a productive gamble…
