The thermonuclear supernova modeling pipeline has been refined for over four decades and has achieved substantial success in modeling various supernova subtypes. Nonetheless, continuous innovation is essential for maintaining supernova modeling at the forefront of computational astrophysics. In this work, we examine a novel scenario, so called thermonuclear electron-capture supernovae. Originally proposed by Jones et al. (2016), this scenario consists of a collapsing sAGB star that only narrowly escape collapse to a neutron star by runaway thermonuclear thermonuclear burning. Here, we explore the specific circumstances under which such a thermonuclear explosion can occur and under which conditions the collapse can be averted by nuclear burning. Subsequently, we leverage this scenario to motivate a long-overdue update to the thermonuclear supernova modeling pipeline, both by increasing the complexity of the physics included, as well as updating the underlying codebase for the latest exascale computing clusters. In particular, we advocate the integration of radiation hydrodynamics and the transition towards a performance portable programming model.
