Yes, you should worry. The gold plating will be thin and porous, as well as dissolving instantaneously, and P-bronze is just one helluva alloy to solder. In fract, all bronzes can be difficult but phosphor-bronze particularly so. It would be necessary to have a thick barrier metal, say 5 µm nickel, overlaid by ~3 µm gold for P-bronze, IMHO.

In no circumstance should this part solder harder than a QFP, for instance. The only issue might be the gold plating.
