I probably don't know enough about the bitbake internals to see how to fix 
my problem with that, could you please point me in the right direction?
I think in case of AUTOREV I would still need some way to automatically 
include a sortable revision count in PKGV, so the actual problem would only 
move from PV to PKGV.
Or do you mean this would allow SRCPV to be removed from those hundreds of 
packages which don't use AUTOREV at the moment, so I can keep using AUTOREV 
for my own packages, without those other packages starting to cause 
problems?

Note that my problem is not 'getting the package upgraded on the target', 
but 'getting automatically incrementing package versions which are 
consistent on several build systems'.

So for me a simple workaround would be allowing BB_LOCALCOUNT_OVERRIDE to be 
defined per package, rather than globally.
Or something similar, which would allow me to use the sortable revision 
count only for those packages for which I really need AUTOREV.
