Yes, it provides node <at> 11.10.0 *plus* its dependency libuv <at> 1.26.0. 

 $ tree /gnu/guix-local-packages/ /gnu/guix-local-packages/ ├──

 node.scm └── node-llhttp.patch

I note the order of libuv packages varies, but versions are 
correct.   Also, should one worry about the "source newer than 
compiled" messages?  I presumed the cached .go files come from the 
official channel, hence older than the sources in 
/gnu/guix-local-packages.
