Support for "exportTo" fields for other namespaces


I have been looking at the documentation for virtual services, destination rules, and service entries and I noticed that there is no support for the field exportTo when the values are not ‘.’ or ‘*’ until version 1.9 [1][2] except for virtual services that the note at the end doesn’t disappear until version 1.11. [3]

So my question is: is it like that? or is it a typo in the documentation?


[1] Istioldie 1.9 / Destination Rule
[2] Istioldie 1.9 / Service Entry
[3] Istioldie 1.11 / Virtual Service
