We use the engines field for application deployment to nodejitsu,
since we need to know what version of node the user prefers their
application to run on. That said, this is for applications and not for
libraries, and I'm not sure it makes much sense for libraries
excepting for special cases where a deprecated version of a library is
known to only work with certain versions (in which case you set the
versions deliberately), which should be much less common now that the
0.4/0.6 jump is complete.
I suppose an engines field could also be useful for binary package
builds, maybe. Not sure.
