The most basic adaptive cruise control is "awesome" in bumper to bumper traffic.

For some reason many manufacturers intentionally disable it at low speeds or won’t let it restart from stop. Super annoying and entirely unnecessary

I understand not restarting from a stop unprompted. There are simply too many situations on the road where automatically moving from a stop may be undesirable in case the driver isn't paying attention. Stop signs, four way stops, yield situations, probably more. Safer overall to make it an intentioned action by the driver.
