Lydia,

If I'm not wront the substituion scenario covers your requirements

{{#property:Pxxx}}                             ==SUBST BY ==>{{#property:Pxxx|label="main label at the time of substitution"}}
{{#property:MainLabelAtSubsTime}}  ==SUBST BY ==>{{#property:Pxxx|label="main label at the time of substitution"}}
{{#property:UnambiuousAliasAtSubsTime}}  ==SUBST BY ==>{{#property:Pxxx|label="unambiguous alias at subst time"}}
{{#property:AmbiuousAliasAtSubsTime}}  ==SUBST BY ==>{{ERROR}} ==> hence the editor can fix it

It looks like covering most of cases without adding extra burden of unicity and keeping existing mechanism

Accessing only via the property's ID isn't enough.
Folks, we want more usage of Wikidata on the Wikipedias and other
sister projects. There'll be a few bullets we have to bite to make
this happen. I am convinced this is one of them.


Cheers
