My gut feel is that this started as an internal project/tool to support the
Intel AMT (Active Management Technology) features, then got turned into an open source project so they wouldn't have to do so much to maintain it internally. Also adds some levels of support for pre-AMT systems, along with phones, etc. I think this is Intel enterprise-focused stuff making it to the general public.
Some interesting capabilities along with the standards. 2 remote control options (theirs plus VNC, some AMT versions include hardware-level VNC). Remote shell. Using any endpoint as an HTTP/HTTPS proxy (e.g. for access to internal management interfaces). Using any endpoint (presumably on the same LAN) to send Wake-On-LAN requests to another endpoint on that network. Remote file browser/management.
There's a commercially-supported version available (based on the open source one).
Sprinxle. Pricing there is $4/month per device which is.... not so appealing. Presumably that drops a lot if you're a large enterprise.
I like that you can download and run your own server instance on the open-source side - I'd not want to run it using their no-charge / hosted by Intel portal for risk of breaches and/or Intel canning the entire department and the whole thing goes away.
The developer is actively involved in Intel AMT development and related areas (now MeshCommander):

Overall, the open-source side might be interesting to investigate, and I could see buying a single-seat license to Sprinxle just to get access to their knowledgebase if it's any good (and if it remains relevant to the open source packages), but I don't see it in production use for most techs here. I could see it being something that an RMM vendor might investigate depending on their existing remote control options. I wouldn't expect Solarwinds (N-Able, MSPAnywhere) or Connectwise/Labtech/ScreenConnect to put resources into it, but vendors who don't own a remote software company might invest time.
