Usually I upgrade my build chroot but I can't swear that I did it
yesterday - so this might be an explanation.

In how far is this different to other dependencies which are not
injected using dh-linktree.  I admit I can not share your point
completely here and I would love to at least see an option to switch
this version binding off (and I would definitely switch it off in all
packages I'm building or alternatively revert my packages to use
dh_links again).

Not only say a word about it but rather warn about it.

Thanks for the quick and helpful explanation anyway
