Not surprising, because it hasn't been switched to ELF.

It's highly dependent on people having time to work on it.
This kind of change is hard to track, partly because the toolchain is
a bit fickle, and having the right version of binutils to play with the
right version of gcc and adding gdb on top of that is well... not always
that simple.
