I don't think this is the first time that the name "zones" are confusing has come up. What to change it to? My vote is in the previous post: DSP RBS (Rule Based Switching).
Now how to change everyone's current Zones to locations and DSP RBS without swamping the boards with how everything just got messed up?
The issue is not the name, it's the functionality.
If I were to treat zones like it was a rule-based DSP system, I'd have 20+ zones and I'd never have a complete playlist in any of them, since each zone has its own playlist.
The point is to have one zone per room or device, and a subset of DSP rules per-zone.
If DSD is played to Zone A, perform DSP 01.
If a Multichannel file is played to Zone A, perform DSP 02.
If a stereo file is played to Zone A, perform DSP 03.
If DSD is played to Zone B, perform DSP 11.
If a file with a sample-rate above 48kHz is played to Zone B, perform DSP 12.
If Multichannel is played to Zone C perform DSP 21.
If any file is played in Zone C and it is after 9PM, enable Night Mode and reduce volume by 6dB.
If an album is tagged with the keyword "binaural" disable the headphone DSP in any zone.
If video height is >1080 play using RoHQ, otherwise use custom-mode video settings - or custom config A and B etc.
Ideally there would be a base DSP config per-zone, and rules would be layered on top of that.
All DSP changes from the zone's default config should be temporary and revert when that rule no longer applies; e.g. playing a binaural track would disable headphone DSP for those tracks, but it would be enabled for any other tracks.
