There have been a number of small, 720p displays that accept "1080p input signals". The EDID is reporting device compatibility/capabilities - how the device manages to deal with it is of no concern to the source. Same answer for TVs with DD5.1 / DTS support - it's there for audio compatibility, the display deals with the signal, decodes/downsamples the audio/video as needed (since the TV still only has two speakers, for example). 4K to 1080p is simple to do - drop every other line and you're done!
(may not be the best answer, but it's cheap!)
The same will likely come about with 4K - HDR support will be nice to have on any display regardless of actual 4K resolution. As the chipsets become available and replace the 1080p models (which happens once the chip prices approach parity), we'll see them in lots of displays - again for signal compatibility.
In the meantime, since 4K content from external sources / set-top boxes is pretty rare - an EDID cheater device for the kitchen TV would at least let the theater work (even though, when playing 4K content, you'll get no picture in the kitchen).
