No it doesn't.  This is almost useless for those who tracks main (they 
may be useful for those who are using quarterly branch, where toolchain 
ports are updated way less frequently) today.

We need a more systematic solution to this, for example the toolchain 
packages should get highest priority at build cluster and once they 
(plus dependencies) are built, they are being delivered to the official 
pkg site immediately instead of waiting for the compiler to finish 
building everything else, then delivered to the package site.
