Keep in mind, that the timedated script is not the only affected script, 
there is at least src:fence-agents as well and there might be other 
packages affected as well as local scripts which expect /bin/sh to 
behave POSIX compliant in that regard.

If this change in behaviour is kept, I would at least expect a big fat 
NEWS entry in the Debian dash package which is shown on upgrades and it 
should probably also update the package description which currently 
still says that it is a POSIX-compliant shell.

Regards,
Michael
