IMO 'vgreduce --removemissing' doesn't look to me like a real rocket science.
Of course if the space on a missing PV has been in-use with some LVs - it gets
a bit more complex - but still as long as you don't care about data adding
'--force' option should usually help (although there can be some room for
improvement - but every coding takes its time - and there are not to many
hands working on this...)
