The most common formats for "loops defined inside an audio file" have
historically been non-WAV (or extensions to wav), such as REX, and
proprietary.
The WAV spec does include the concept of a playlist, consisting of cue
points and lengths. By themselves, these don't really define "loops" in a
way that is generally going to be clear to the user.
libsndfile can definitely read these from the file, but i'm not sure what
an app would do with them. providing a sample with a loop point(s) defined
would be good.

Hey fellas!
I notice that no Linux samplers seem to support wav file loop points. All
Windows DAWs that I have used support the format and there are a lot of
samples out there with perfect loop points which is very useful.
I have no idea whether this is part of the spec or not but these looppoints have been
used for more than 15 years, that's for sure, since some
of these sample collections have been around during tracking days. I did
find something on loops here:

But I think you, devs, know better than me anyway.
I think it would be great if LMMS, samplers like Petri-Foo would support
this, as this adds a lot of functionality. Many sample collections provide
perfect loops and it is tiresome to have to try to remake it by hand each
time, while in some software it is simply impossible at all.
What do you think?
ps: I can provide you with a sample example with loop points
