Here is the section

424.9 General. Permanently installed electric baseboard heaters
equipped with factory-installed receptacle outlets, or outlets
provided as a separate listed assembly, shall be permitted in
lieu of a receptacle outlet(s) that is required by 210.50(B).
Such receptacle outlets shall not be connected to the heater
circuits.
Informational Note: Listed baseboard heaters include instructions
that may not permit their installation below receptacle
outlets.

The house we now live in was built in 1977. When we moved here in 1982 I noticed that there were wall receptacles located about 6 inches above 3 baseboard heaters, one 8 ft. in the living room and 2 4ft. ones in the bedroom and den. Not being a licensed electrician at the time I thought nothing about it. They have since been removed as we now have switched to a heat pump. Could they have been permitted under the then current code cycle?
 
That informational note kind of suggests there possibly could be units that have low enough output temperature that they may allow a receptacle above them. I never seen one if there is such a thing.

Lived in a house with hydronic baseboard heaters once, they didn't get nearly as hot as electric baseboard heaters, also needed nearly entire length of wall because of it as well. There were receptacles above those.

Same here ...that type of heat is much more even and comfortable than forced air heating. The water temperature out of the boiler (never understood why they called it a boiler) was typically less than 180°F, so the heat from the baseboard was not enough to be an issue for receptacles above it.

Just my guess but the main predecessor to these was the old cast iron radiators and I believe they generally did have a real boiler on those systems.

They did, because the system was designed to use steam, not hot water, and often had single-pipe systems where the condensed water flowed back through the same pipe as the supplied steam.

Steam is theoretically more efficient, because, like Freon, the medium changing state between liquid and gas absorbs or emits heat to a much greater degree (sorry) than mere temperature differences.

Steam don't need a circulating pump either, though if return isn't or can't be designed for gravity flow condensate return pumps can be required.
