Personally, no, but the GP did say "allowing any arbitrary scale" and that's what I was referring to. Why Apple does not allow 150% is beyond me because it is quite reasonable. But I can understand why they don't allow users to enter a value like 168%.

It is absolutely not reasonable. HTML tables with horizontal grid lines will appear to have varying line thicknesses when in reality they are all set to the same width.
