Was there a historical requirement to announce altitude, temperature, etc? It is a common experience of flying on commercial flights that pilots announce certain flying conditions, including altitude and speed.

It has been previously asked on Aviation SE why pilots announce the cruising altitude of flights.  The answer there suggested there was "no real reason".

On Quora, it was asked similarly why pilots frequently announce altitude, outside temperature, and speed.  The first answer there suggested it was previously a historical requirement; however, the answer does not provide a reference to these requirements.

Has there been historically, or is there now, a requirement in any major jurisdiction (FAA, EASA, etc.) for the pilot (or flight crew) of a commercial flight to announce altitude, outside temperature, speed, wind, or weather conditions?  If so, what was/is the specific text of the requirement?
As this may be most common among airlines, this is not a requirement whatsoever administered by the FAA or any other aviation governing body. This is more so considered a tradition usually when the plane reaches cruise or is about to land. No such modern airline or any airline in the past has required this to be announced to its passengers.
