Unfortunately, this hasn't been the case since HF16. Every hardfork since then has come with all kinds of things bundled together. They see each hardfork as a risk, but of course, paradoxically, bundling all kinds of things into hardforks actually increases the risk.
All I'll say is - a) SPS code was completed a long time ago, and b) they are not talking about releasing SPS hardfork, but rather debating EIP and c) if you see their GitHub activity, they are coding in the EIP changes for the next hardfork. Make of that what you will.
