I find it unfortunate. But it also can be difficult and time
consuming to reimplement an assembler for those back ends, so
I can understand why it isn't a priority.
LDC in fact implements DMD-style inline assembly (occasionally
there are bugs, though, as it's a complete reimplementation).
I don't think it would be unreasonable to work towards a common
D ABI on the various Posix x86_64 systems, but given that DMD
comes with its own bespoke exception handling implementation
which doesn't really make sense to implement in GDC/LDC (as
libunwind is the platform standard on Linux/… anyway), there is
not really much motivation to start work on aligning the other
parts of the ABI either.

I'm reinventing it right now for SDC, so it indeed make sense.
