Precisely.

Periodically someone suggests "solving" weak debugger support for
debugging inlining by offering compiler options to suppress information
for inlined functions which come from system headers.  I think this,
like that, is exactly the wrong way round from an implementation
perspective: the debugger should be able to offer this choice.  Both
for macros and for inlined functions.

A wise and friendly debugger would probably use the default of hiding
things from system headers, and you'd get exactly what you've asked
for.
