I don't think that should be a concern because if the ownership of
/var/spool/exim4 needs to be non-root then it should be set in the
postinst script. That would be true upon the first installation too,
right? Upon a removal, id scramble, installation the postinst script
will set the correct permissions, right?
Example from the postfix postinst script:
mkdir -p $MAILDROP
if ! chown postfix:postdrop $MAILDROP 2>/dev/null; then
addgroup --system postdrop
chown postfix:postdrop $MAILDROP
Example from the bind9 postinst script:
getent group bind >/dev/null 2>&1 || addgroup --system bind
getent passwd bind >/dev/null 2>&1 ||
adduser --system --home /var/cache/bind --no-create-home \
--disabled-password --ingroup bind bind
Example from openssh-server postinst script:
if ! getent passwd sshd >/dev/null; then
adduser --quiet --system --no-create-home --home /var/run/sshd --shell /usr/sbin/nologin sshd

Debconf should be available for those types of questions of the user
at installation time. However if the user selects a non-dynamic id I
don't know how the package could know what global one to use other
than to coordinate it. Asking the admin installing the package for an
id seems like a big step backward.
Also, packages shouldn't call adduser if the user already exists.
