Are there any practical reasons for this other than no one actually cared to keep ABI synced?<br>

Also, GDC/LDC/DMD32/DMD64 use different portions of the druntime. For instance, if you are concatenating two arrays (a[] ~= b[];) and compile the application with DMD 32bit, and linked to a druntime built by GDC then you'll get undefined references to '_d_arrayappendcT' (for GDC, this function is useless as is not portable, so we version it out)<br>
