I guess it is worth mentioning that the typical lifespan of an aircraft is around 25 years. Planes are so expensive that they need to be built to last and they need to be operating to make money.
It is rare that a company would stop flying the plane just to update de phone jacks.

Additionally a model of aircraft will probably be in production for 20 years, so for each model there will be 40 years or so from the first one rolling off the assembly line to the last one being scrapped

Funny. I’m surprised the older one doesn’t have 1/4” jacks and a personal 8track player for your comfort.

Every six to ten years, aircraft go in for a "D check", where they disassemble the whole thing, replace anything corroded or worn out, and put it all back together again.
The lighter weight "C check" is more often, but is 4000+ hours of time to do.
If you're doing the once-a-decade style service, it feels time to replace the plugs from 25+ years back. ;-)

Fair, but the 3.5mm headphone jack is over 70 years old and was made incredibly popular by the portable WalkMan cassette player released 40 years ago. Airlines installing unpopular or proprietary plugs in 25 year old aircraft still seems absurd.
