Actually, it provides information that can be used for both. It
indicates if the oil is still functioning properly so that one can
adjust oil change intervals as necessary. Of course, you can choose not
to do so and in the case of aircraft, you may be legally bound to follow
a specific maintenance schedule. That's not true of privately-owned cars.

Wear always happens. The oil analysis will point to particular areas of
wear and indicate whether there is any abnormal wear that needs to be
addressed.

While your other points are absolutely valid, I have to take issue with
this one. There are no "crappy" oils on the market, at least not as long
as you buy SAE certified oils (which most are). One can argue and
nit-pick and hypothesize that X brand is better than Y brand, but if
it's got the SAE certification on the label, it's good enough for any
car. About the only significant differnce in oils is between natural and
synthetic, with the latter being demonstrably superior in most test
criteria. However, the real-world difference is more in the realm of
"extra insurance" than "clear advantage", since natural oils are
certainly good enough. Perhaps the only clear advantage of synthetics
for normal driving is that you may get better fuel economy, especially
in cold weather.

I tend to agree. If an oil meets the certification criteria, it is probably
just fine. I have long felt that some oils tend to varnish the engines
a bit more than others, but this is a subjective and anecdotal comment.
Synthetic lubricants have some interesting test data, not all of which
apply to the primary job of lubrication. I am sure they are quite good,
and may use them in the future, but not to delay change schedules.

True, but during the warranty period it is the manufacturers that need
to be convinced. I'd change my Hyundai oil at 10K miles if I wasn't
worried about voiding the warranty. And with the 100K warranty, it
means I can't start my 10K intervals for a long time.

It is actually both. Yes, the main benefit for airplanes is avoiding
engine failure, but you can also extend drain intervals with oil
analysis. For large truck fleets, the analysis is typically all about
extending drain intervals.
