Yes, not only D but any language that currently falls here (https://github.com/llvm/llvm-project/blob/main/lldb/source/Plugins/TypeSystem/Clang/TypeSystemClang.cpp#L106-L112). AFAIK, rust have immutable variables too. Since I'm working on a DWARFFASTParser for D this won't affect it in the future, but for languages like Rust that uses the Python API and rely on Clang DWARFParser, this could be beneficial.
I know the change is well intended, but the Rust support is 100% untested and completely broken (it can't deal with pretty much any non-trivial program from my recollections). So I would split out the Clang changes (which probably require some longer discussion) and just keep the Type/DWARFDIe changes (which look good to me).
