AB - <p style="text-align: justify;">This note aims at providing a rather informal and hopefully accessible overview of the fairly long and technical work [F. Ancona et al. ArXiv:
2401.14865], where new global-in-time existence results for admissible solutions of nonlinear systems of conservation laws defined in domains with boundaries are established. The main novelty of that work is that the solution is constructed by taking into account the underlying viscous mechanism, which is
relevant because, in the case of initial-boundary value problems, different viscous approximations yield in general different limits. In the present note we
will frame the analysis of the paper mentioned in the relevant context, compare the main result with the previous existing literature, and touch upon the
most innovative technical points of the proof.</p>
