I don't see this as a major objection. The specification of the strfrom functions is clearly derived from snprintf, which is most obvious in the format argument.

I agree; this would be acceptable.

I don't think we need to have strfromf.  C programmers are quite used to using double formatters for float values at this point.  It's in the reserved namespace, so it can easily be added at some future point if appropriate.  If someone felt very strongly that there should be a float %a format of the form 0xX.XXXXXpEEE, and wanted to take on the task of defining everything for strfromf, I wouldn't object to it's inclusion, but it seems like a whole lot of change for very little benefit.
