Keep in mind that Sonoma is not in public release (only recently public beta), and that not all devices that can run the prior solution will necessarily support running Sonoma. In addition, many users will not update to Sonoma for a while to ensure stability, hardware compatibility, etc. - particularly where there is a dependency on stability and compatibility for livelihood.
As such, the pre-Sonoma solution would be relevant to a decreasingly significant number of users for some time yet.
