Thanks. So it seems 'Flash Nuke' is now a universal UF2 for Pico and Pico 2 which is good news.
And that "maybe we should treat separate families in a UF2 independently" is exactly what I've spent the last few days doing, parsing the UF2 into per-family images in my own tools.
I have strictly per-family so 'RP2XXX_ABSOLUTE" is a family in its own right rather than added to a single RP235X image because the only use of it I've seen is the 'Errata-E10 fix' right at the end of memory which would otherwise make all ARM images 16MB. In fact I have that fix as a separate virtual family to make things easier.
And it seems I am going to have to look deeper into how 'Flash Nuke' does things -
