Description
Note: AI-assisted (written with Claude).
The add_piecewise_formulation docstring asks for use cases while the API is evolving, so a one-line cross-reference: PyPSA/PyPSA#1914 exercises snapshot-dimensioned breakpoints (a (snapshot, _breakpoint) DataArray per entity, verified working on 0.9.1 with the lp tangent method) to express time-varying piecewise marginal costs. Nothing to change here as far as I can tell; just flagging that the proposal relies on that broadcast behaviour staying supported.

Research direction
Start with the add_piecewise_formulation docstring and PyPSA/PyPSA#1914, which is cited as the use case for snapshot-dimensioned breakpoints. Confirm whether a cross-reference is wanted and whether the broadcast behavior should remain supported; done is a clear documentation decision or update.
