The US Ford site no longer shows the 2017 Fusion as being a "future vehicle" - it can now be configured online from the top down. The Canadian site hasn't been updated yet.
And with that, I learned some awesome news - you can still get the active park assist (which also includes perpendicular parking) on the SE model (previously, the "future vehicle" configurator implied otherwise and that had me worried).
Unfortunately, the LED headlamp option is restricted to Titanium and higher. The SE model still gets the LED daytime running lights and the LED taillamps, so SE buyers aren't stiffed too much, and you can always get HIDs retrofitted later (I have a set on my 2013 SE).
There doesn't seem to be a spoiler delete option on the Titanium anymore - hopefully dealers can still take care of this.
I'll probably upgrade in a year or two, and will be monitoring the certified pre-owned market as well.
