Yes. pdfTeX <1.10a didnn't care for x and y; you only got a
warning from the xpdf layer when y was greater than the y
supported by xpdf. I want to get that behaviour back to be
backwards-compatible.

Then we will need a major rewrite of pdfTeX anyway, as this will
break almost any pdf consuming application anyway (see PDFRef H.1). 
Of course a float for x would be nice, but it's currently not
needed and there is no code in pdfTeX yet to scan float
parameters.
