Yes, it is. This suggestion was under the "by hand" assumption.

BTW, debian/substvars is deleted by dh_prep (called in install), so the
echo line above should be done at the beginning of binary-$whatever
instead (or at the end of install). Or if you call explicitly
dh_gencontrol, the variable can also be given as a commandline argument.

Currently, yes. But at long term, no. See #500036.
