Stupid question: is installing the 'Resize VM Boot Partition.pkg' supposed to just run the resize script on Big Sur 11.7.3?

The only thing that seems to happen is to add a receipt. The boot volume didn't get resized.

Correct, it runs the following script:

https://github.com/rtrouton/rtrouton_scripts/blob/main/rtrouton_scripts/resize_vm_boot_partition/resize_vm_boot_partition.sh

Do you have any logs? Since you were running it via an installer package, the output for the resizing should have gone to /var/log/install.log.

Thanks for your prompt reply. I didn't know about /var/log/install.log before. Here's what it shows, with date/timestamp removed for brevity:

./postinstall: Started APFS operation
./postinstall: Error: -69743: The new size must be different than the existing size

I get the same error after separately downloading and running _resize_vm_bootpartition.sh. I guess the macOS installer doesn't check the return code from the postinstall script as it declared Resize VM Boot Partition.pkg installed successfully.

I know the error has nothing to do with Resize VM Boot Partition.pkg and I don't have a solution but in case anyone else runs into this, here's the diskutil info. I was trying to expand the startup disk to the full 107.4gb. I can use _resize_vm_bootpartition.sh manually to shrink it, then expand it, but can't expand it beyond the 53.5gb already defined.
