Right. Maybe "defunt" column should be in my proposed lcr_gws_grps
table rather than in lcr_gws table.

Another possibility is to split this concept into "enabled gw" and
"available (not defunt) gw". "defunt" would mean that it has been
detected to fail, so it would make sense within the lcr_gws table. In
the other side a new column "available" in the proposed lcr_gws_grps
table could contain a "enabled" field, so LCR just uses/loads it if
such field is 1.
