I wish they made....

Led lamps that fitted generic lanterns (with thier standard bases) gave the same sort of colour and equivalent light output and allowed us to keep our patt.743's p.123's prelude/quartet, solo follow spots etc in use. Rather than having to bin them for a lack of lamps in years to come!!!!!

The City Theatrical ShowBaby uses a male XLR with a single contact to tell the unit whether it's a transmitter or receiver. But unless you add some electronics it wouldn't be any use for this application.

A US company made just this, for Par 64s. They could dim from the existing dimmers so no cabling / infrastructure changes required. 

However they ended up being the same cost as a pretty decent LED par, so I suspect most buyers would go down that route, and get colour mixing etc. into the bargain.

Is that an actual physical switch contact like inside a jack, or do they use some other method to detect an ongoing DMX chain?

It's a physical microswitch in the body of the socket.

The "standard bases" part is simply impossible for anything other than a PAR-style lamp.
LEDs run cool, but the diodes have to stay cool or they die very quickly.

That said, retrofits do exist, eg the ETC Source 4WRD that replaces the burner, lamp and reflector.

Most of that is the massive heatsink, heatpipes and related gubbins to keep the diodes cool.

It's always surprising to me that even the "super energy efficient" LEDs convert about 60% of the input energy into heat which has to be removed from the LED to keep it working. This simply cannot be done in an object the size of a halogen lamp, so anything retro-fit has to be much bigger with built in fans or other method of removing the heat to outside the fixture.
