you're just shifting things around here. of course there doesn't need to
run a SPARQL engine underneath every implementation, but if our query
language is close in complexity to SPARQL, then service implementers
without native SPARQL back-ends will have to implement the mapping, and
will get close to having to implement SPARQL. which we probably don't want
to place as a burden on every LDP implementation.

all depends on where you're coming from. it should be approachable for as
many people as possible, and not just people with a five-year background
in [SPARQL|XQuery].

my suggestion would be to try really hard to avoid SPARQL being a
normative reference. illustrative in the implementation guide: yes.
