Well, it hasn't really been "sold" as a library, but it is open source (BSD
license) and would be fairly easy to separate out if another client wanted
to use it, so:

Very lightweight.
No external dependencies
Designed for asynchronous operation.
Can do cross-origin fetching (including credentialed CORS) on most browsers.
Empirical testing suggests it's pretty tolerant of any DAS XML "in the wild"
at the moment.

Missing support for a few things we don't currently use in Dalliance (e.g.
DSN requests, structure extension, etc.).
Currently not easy to cancel in-flight requests (although that's something
we're working on).

Yes, file a ticket in Github or e-mail me.

Linked to Dalliance releases, current version is 0.5.7 (0.6 should be out in
the next few days, but doesn't have any major changes to the DAS backend).
