> Services will likely have different limits in the number of levels of depth they support in queries.  For example:
> •	Filter on far navigation (e.g. Manager/Manager/Title eq ‘Director’ )
> •	Nested Any (e.g. Reports/any(Reports: Reports/any … )
> •	Deep expansion 1:M  (e.g. $expand=Reports, Reports/Reports)
> All those filters are syntactically correct, but create undue server-side load, so services are likely to impose limits on the number of levels of depth for such expressions.
> Is this something services should be able to report in Capabilities?
