If openin_any = p is in force the calling tex system wouldn't be able to

I think that's compatible with openin_any=p (which actually is in force
above) otherwise we would (I think) have to add a call to

kpsewhich -var-value 'openin_any'

to disable --all in that case.

or using the lua interface rather than calling the command

  if (kpse.var_value('open_in') ~= 'a')
