It has been pointed out that the SM component was turned off for a very long time, so it was not used and not tested. Moreover, when enabled the performance are below tuned, so there is no reason to keep it around.

The good news is that there are two possible replacement that are up to review and merge (ACOL and XHC), so at the developers meeting in Austin 2024 we decided to remove the SM collective component.
