TreeView widget - designed for general use?

The TreeView widget seems to do okay for the purpose it's used for in 
the IDE, but is it designed for us to use in our projects as a general 
solution for tree views?

If so, perhaps I should file a series of bug reports, unless you folks 
know of a way to work around these:

- Frequent "chunk index out of range" errors when double-clicking lines,

- Sorting issue when nested arrays may have one level of numeric
   keys and another level with text keys; we can use numeric OR
   text, but no way to different sorting for different levels.

- Scrollbar doesn't look like anything I've ever seen before except
   maybe macOS; on Linux the scrollbar looks nothing like the wonderfully
   rendered LC-native scrollbar control, and is also inset from the right
   side by several pixels.

- Any way to switch the disclosure triangle to "+"/"-" per the Windows
   HIG when running on Windows?
