11-current becoming 11-stable

[tech-lists]

Hi,

I have a desktop that has run 11-current for at least the last year. I 
periodically rebuild kernel and world to keep on top of things. As it's 
a desktop, there are lots of ports installed. These are installed via 
the older cd /port && make install clean way, rather than poudiere.

Basically I'm asking that, when 11-stable becomes available (as far as I 
can see, it's still at PRERELEASE), is it worthwhile/advisable to 
recompile all my ports after doing the make world & make delete-old dance?

thanks,
