Most of them are, but not sure why that matters here (the gain is
almost negligible and mainly interesting for the C++ parts - as
all D files are compiled to a single object file anyway).

Right, it's still experimental and has issues.

That's only true if (mostly non-templated) functions in
druntime/Phobos are to be cross-module inlined, just like any
other library. In that case, you can simply use
with LDC builds shipping with LTO druntime/Phobos and don't have
to recompile druntime/Phobos manually anymore.
