Yes, OS-native apps can be made in many languages, including scripting 
languages like LiveCode and JavaScript.

My explorations here are less about the programming languages one might 
use to make them and more about the delivered result, whether the app is 
its own executable or lives within a web browser executable.

More specifically, the distinction is that the app is delivered within a 
browser, since even OS-native apps can have most of their UI and code 
downloaded from a server just like web apps do.

If the web client technology stack (JavaScript/HTML/DOM/CSS) is a "snake 
pit", do we really want to increase dependency on snakes in LiveCode?

If I want an asynchronous progress indicator like a spinning wheel, 
should it be necessary to include and embed an entire other web 
application process just to get that?  Is that the story we want to tell 
new users?  I'd much rather have an async playback option for the LC 
engine's handling of GIFs, which already covers the other 95% of what we 
need very well.

Same for broader use-cases, like smooth transition effects of the sort 
CSS3 now does so well.  Those are also now so pervasively expected by 
users that it benefits the LC platform more to have as much of that as 
practical right in the engine, rather than limited to one specific 
widget that requires us to leave LiveCode and program it in JavaScript.

A sense of smooth liquid flow is the hallmark of modern UI.  If support 
for this were limited to one widget that requires JavaScript, we might 
as well use the other tools you mentioned above.

Fortunately it seems some of the work needed for the DG update will help 
with some of this.

Related, Jacque's request for swipe transitions was well received, but 
oddly its status was changed to "Hibernated":

I hope that's only momentary.  Swipe transitions are no longer merely 
optional for mobile UIs, and the level of effort required to work around 
that with groups diminishes many of the advantages of choosing LiveCode, 
lowering LC's score when potential new users do a comparative 
evaluations of tools. I may be a dreamer, but I'd like to see LC match 
or exceed capabilities in such comparisons.
