AFAICT the libopenmpi40 transition unblocks most things and should work. Issues that need addressing:
(1) #1087988 [S|  |  ] [src:hdf5] hdf5: incomplete openmpi removal on 32-bit architectures

Needs an answer similar to adios/netcdf-parallel etc with d/control created from d/control.in

(2) #1079106 [S|+|  ] [boost1.83] boost1.83: Autopkgtests fail on armhf due to OpenMPI changes

(3) #1087853 [S|  |  ] [src:boost1.83] boost1.83: autopkgtest regression due to new CMake deprecation warning

boost 1.83 has lots of rdeps. (2) has a patch, (3) needs work.

(4) gyoto/yorick: looks like this is a release manager call. gyoto fails on math regressions with yorick, but my attempts to rebuild yorick hang.

(5) mpi4py fails to build with py3.13 (due to cffi dependency). Builds ok with 'nocheck' allowing more of the stack to build.

(6) elpa also needed a nocheck build (unrelated to openmpi40).

I think the openmpi40 transition should proceed to clear up the build issues. mpi-defaults is essentially done, and openmpi-rm won't progress without the rebuilds. The only issue with openmpi-5.06.-1 is  #1087800, for which there is a one-line patch to fix s390 which I'll apply in openmpi-5.0.6-2 if the RMs say ok.

Commander Vimes didn’t like the phrase “The innocent have nothing to fear,”
 believing the innocent had everything to fear, mostly from the guilty but in the longer term
 even more from those who say things like “The innocent have nothing to fear.”
