I think rather than keeping the problem on the LSL side, it would be more

Which would not remove, at all, the problem of having to use sensors
in an object in order for the object to detect who is nearby. It would
be much more feasable to have a function return a list of avatar keys
in the sim, and to call this function once whenever the agent count in
the region changes.
I think the best solution would be to allow sim-wide sensors
(llRegionSensor() ?)... This would remove the need for probes, just like
llRegionSay() suppressed the need for llShout() relays in the sims...

Sensor events are kind of weird. They were designed specifically to
give a real-world quality to gathered data. If you have a sensor in the
real world, the data it can pick up is generally directly related to
where the object is and some range that it can sense information, and
probably a direction. There are definitely uses for this kind of
information gathering in Second Life, "what objects are near me" and the
various permutations thereof are definitely useful.
However they do have problems. They are limited in what data they
collect since they scan and store a snapshot of the data with the script
- we can't really extend how many results or what data is gathered just
because of the memory footprint involved. The legacy script formats add
additional difficulties that are less insurmountable but still trouble.
By their nature they are at least a little more load intensive than just
accessing data the region already has in memory would be. If you
extrapolate from this just a little bit you can think about why region
wide sensors wouldn't be that great. We could still only return the 16
results and the existing types of data.
As has already been suggested in this thread I believe, we are much more
likely to investigate non-sensor calls that directly access information
the region already has in memory and don't try to mimic real world
behaviors or the sensor pattern. llGetAgentCount() or
llGetAgentsInParcel for example, that could return data directly. I'm
not saying we are working on these or even have plans for them, and
there may be privacy issues that come into play for some of these types
of calls. I'm just saying that I think this is more likely to be the
direction we head than extending or mimicking the llSensor pattern.
