Thanks for asking the question. I have no objection to the driver name change and haswell is not used in commercial products outside of Intel. You have a point that most of the machine driver module names make limited sense in hindsight, but it's better to leave them as is. Changing them will increase confusion IMHO. We have scripts to remove/re-insert modules and every time we add a name change we break the test suite. This happened when we changed all the PCI names, it wasn't pretty. See e.g. all the 'obsolete' references in those scripts to keep them working across kernel versions. https://github.com/thesofproject/sof-test/blob/main/tools/kmod/sof_remove.sh#L134 we also enable dyndbg with /etc/modprobe.d/sof-dyndbg.conf deployed on test devices, if we change module names it gives everyone involved in CI/testing more work. And last if you Google a bit you'll see references in a couple of wikis and bug reports to modprobe snd-soc-sst-broadwell, so if you change the module name you make the information obsolete.
