That is my recollection as well.

Even more so, it can be disastrous, causing traffic blackholing, if 
you're editing communities or attributes required to "make things go" 
and need to do this in a multi-step way e.g.

route map blah 10
   ! There's no "no set community 1:2", thanks IOS
   no set community
   ! oops a route refresh happens now I've sent all my routes
   ! with no community, and the community is necessary in this case

   ! a few seconds later...
   set community 1:3
