You can sometimes, you can't others.

> Lots of voting systems are based around the same input assumptions, i.e., people are submitting a rank-order of preferences

But FPTP is not based on that input, so changing from FPTP to a more proportional system (many of which rely on that kind of input) provided a clear opportunity to have a clean break without false familiarity.

The false familiarity is FPTP -> PLACE.

Ah! I misunderstood. You're talking about the possibility of "check one, go by that candidate's endorsed ballot". (Something that could really be added to just about any voting system; I hadn't really considered it as essential to PLACE in particular.) Yeah, that's an interesting point against that feature, then. Hadn't considered that.
