Bypassing rename traces, feature or bug?

The script below uses a detour to rename a proc. This detour does not trigger any rename traces, as would have occurred if [rename name_1 name_2] had been used.

Is that intended behaviour? (i.o.w. is a follow up as a bug report desired?)

% proc name_1 {} {}
% proc handleCmdTrace {args} {puts $args}
% trace add command name_1 delete handleCmdTrace
% trace add command name_1 rename handleCmdTrace
% interp hide {} name_1
% interp expose {} name_1 name_2
% info procs name*
name_2
