I'd like to hear opinions from C and C++ FE people as to why the current
state illustrated in comment #6 makes sense and if the behavior can be

The hard part with changing the C frontend to behave like the C++ frontend
is to preserve the debug info for the typedef.
The C frontend consistently uses DECL_ORIGINAL_TYPE to refer to what a
TYPE_DECL was

The only difference I see for typedef struct { } T1; vs typedef struct X { }
T1;
when looking at its main variant (or recursively DECL_ORIGINAL_TYPE) is
type_decl 0x75b2be60 X
type record_type

The following seems to work at least for the testcase:
