Comment:

 Hi Karsten - interesting! I didn't realize you were considering this too.
 Adding Isis too since she's interested in this topic as well.

 Descriptor creation has been on my radar for quite a few years (#10227).
 Stem and BridgeDB need it for their unit tests. Stem filled this need with
 test helpers, and Isis did so with her own library called
 [https://pypi.python.org/pypi/leekspin leekspin].

 Descriptor generation fits nicely into Stem's API so I'm adding it now so
 we can deduplicate this effort. So TL;DR is...

 * At present the only use of descriptor generation I'm aware of is
 testing. That said, we might find other uses too.

 * There's two parts to descriptor generation: creating valid descriptors
 and signing it. Stem presently supports the former but not the later
 (however, leekspin can). I'm looking into that next.

 Cheers! -Damian

 PS. Once again kinda sad we keep duplicating each other's efforts. Seems
 like a waist to keep repeating each other's work... :/
