The problem is, there's no one size fits all here.
Different upstreams do wildly different things. 

Some have "stable" releases and "dev" releases before that. (Like gnome)
Some just mix features and bugfixes into a single stream.
Some only seem to have prereleases and take years to actually do a point
release. 

etc. 

So, asking that "dev" releases use different options I think would just
result in a bunch of confusion along with a mix of things with some
using frame pointers and some things not.
