The soa-dev mailing list hasn't been used for a while and I'm concerned that it's too easy to mistake it for the soa-pmc list (further, I'm not sure that having the list adds any value). I think that it makes sense to retire it.
If the PMC agrees, can one of you make a request to the webmaster to retire the list via bug on Community/Mailinglists ?
