I can confess I return to Nginx after long many years of a divorce and 
this curious fact - if Nginx cannot do that - will be a surprise to me.

I thought such a "feature" would be in Nginx by now, if not devised by 
developers than included by popular demand - looking at the 
options/params to 'listen', something like 'remain' or 'insist' which 
would instruct Nginx to start & continue to work and hook onto the IP 
when/after it appeared(but also continue to work after IP disappeared)
