OK, this is where I have read they are used but if they are noisy that counter indicates using them for audio. Starting to look like not needed is the consensus.Don't use them for audio
When I was student at Marconi back in 1985, I was told that tantalums were banned from military electronics due to their tendency to blow up and short out the power supply. Probably a different country's military!All the military electronics I designed required the use of tantalum electrolytics, since standard aluminum electrolytics were considered not sufficiently reliable.
As long as precautions are taken to prevent overvoltage and high surge currents, they are very reliable.
I wish I remember, but I think it was in Cyril Bateman's articles in Wireless World.Where have you seen data that they are noisy?
Where I was working at the time, the company shifted from industrial/medical/telecom to military after the 2000 tech crash. Back then, tant caps were common and sometimes required. Somewhere in the 2005 timeframe things started shifting away from tant, and by 2010 they were banned (without explicit sign-off) in the RFQs we were seeing.When I was student at Marconi back in 1985, I was told that tantalums were banned from military electronics due to their tendency to blow up and short out the power supply.

Two small points that have nothing to do with caps.I'm looking at an audio amplifier to replace the piezo earpiece for a crystal radio.
