Option to make individual aligned equations flush left like flalign

Is your feature request related to a problem? Please describe. I would like to align equations, but not have them centered, but “flushed” left like the flalign environment. I doesn’t seem like the provided aligned environment supports this.

Describe the solution you’d like: Maybe provide a flaligned environment?

Link to or name of a (La)TeX package that provides the same feature: flalign from amsmath

Describe alternatives you’ve considered: I haven’t found any alternatives that can do this.

Additional context:

Just to clarify: extending the explanatory text to span the width of the equation in my picture above is not currently possible, but would be with flalign, which just needs to be implemented? I think I initially misread your comment and thought I could achieve this with {align} but could not.

Would be nice to see after so long 😃
