I don't, but I just checked the NumPy version that comes with various Linux distros so we can see what people are likely to have. There is no Ubuntu long-term support release that ships 1.5, only 1.4 (10.04) or 1.6 (12.04) [1]. Debian doesn't list 1.5 for any of its releases either [2]. CentOS 6 ships 1.4 [3], while CentOS 7 ships 1.7.1 [4].
Thanks for checking. The most recent Ubuntu LTS and CentOS releases are good data points in general I'd say. In this case Ubuntu (and Debian stable) are on 1.6.x, so keep that but drop 1.5.x then?
I'd say so.

I think never versions of Scipy should just target maintained versions of Numpy, for some definition of "maintained".
In principle only the last released numpy version gets new bugfix point releases, in exceptional cases maybe one version further back. So there's a good chance we'll get a numpy 1.9.2, little chance for a 1.8.3 and close to zero chance for a 1.7.3. I don't think that we can consider dropping numpy 1.7.x or 1.8.x support.
NumPy releases are not always backwards compatible. Supporting an earlier version makes it easier for users to migrate their code. It's also easier for buildbots (Travis) if they can fetch a prepackaged NumPy.
