I believe this is true already? Rust used to pretend to be C, and got breakpoints/debuginfo for free. Python scripts could help with pretty printing. I'm not sure of subexpression evaluation is something a gdb Python script can do, but I see no technical barrier to this. Having it in gdb itself means less work for people who want to use it. Rust ships with gdb/lldb pretty printers, but not everyone knows about them.
