Note: this is already effectively included in my barebox unification series:
<20250526101147.1953428-5-rhi@pengutronix.de> (2025-05-26, Roland Hieber:
"[DistroKit] [PATCH 05/11] v7a: stm32mp: switch to upstream barebox recipe") 
(where the size of the partition is removed in favour of specifying it in the
fit image config).
