I think all FAIR researchers and engineers are aware of the NC-CA license limitations.
They still use it because releasing the code for an already approved paper under NC-CA is super easy (~ self-approving by clicking a few buttons) vs following a slow open-sourcing process needed for the MIT license (includes approvals from a sponsoring director or two, committing to support the code for at least a year, etc). Releasing under MIT can easily take a few weeks with each stage requiring finding someone responsible and chasing them across time-zones.
The best practice seems to release under NC-CA and re-license it later under MIT. Maybe this will happen here, too.
