Is there any way to get it to print each module ID only once?

If there's a trivial way to do that, then perhaps it should be done, but for
now, this patch series isn't as obnoxious as the previous versions. It only
affects stack traces, and I'm fine with that.

True. Printing the id in the module list was horrid.

The real downside is all the extra text that will overflow the
in-kernel buffer.
At least it shouldn't be extra lines causing screen wrap.
Unless the variable names are long - hi rust :-)

Note that the ID is printed only when CONFIG_STACKTRACE_BUILD_ID
is enabled. It will be used only by some distros/vendors that
use it to download the debuginfo packages.
