Of course. The question is whether we bump up the file format just for the
nicefrac change.

We had that problem with the wasy package. It conflicts with some other
packages. Some have workarounds, so that a certain order of inclusion needs
to be honored. This can't be done if the wasy package is automatically
loaded, and conflicts with some user loaded package.
The solution for this problem is for now: Don't load the wasy package
automatically, let the user load it manually.
I don't know at all if nicefrac could be problematic, if somebody knows that
this is not the case then all is fine.

You could provide your own nicefrac command in the preamble for example. Or
you could load it manually (see above), or there is another package that
provides a nicefrac command.

I think we should in general avoid to add new packages to LaTeXFeatures
unless the already existing conflicts are solved and we have a more
flexible package loading mechanism. The more package syou load
automatically, the more conflicts can arise.
