That's a bad idea. You can't comment out some intermediate line.

ifconfig_bge0_alias0="inet xxx"
# ifconfig_bge0_alias1="inet yyy"
ifconfig_bge0_alias2="inet zzz"

will result in applying "xxx" only.

but this is even worse:

ifconfig_bge0_aliases=" \
  inet xxx \
#  inet yyy \
  inet zzz \
"

It results in an syntax error.

So I do use:

ifconfig_bge0_aliases="${ifconfig_bge0_aliases} inet xxx"
# ifconfig_bge0_aliases="${ifconfig_bge0_aliases} inet yyy"
ifconfig_bge0_aliases="${ifconfig_bge0_aliases} inet zzz"

For _ipv6 it's different, because you need at least one _ipv6.
ifconfig_bge0_ipv6="inet6 xxx"
ifconfig_bge0_aliases="inet6 yyy"
