PNG is the correct choice for at least 99% of graphics generated with Inkscape.
Ah, No. Not if you care about file size. I work with Inkscape professionally daily for web, print, and design. I use png about 30% of the time. For web, it's more like 10% of the time because of gradients and raster images mixed in with the vector shapes (for auction and listing graphics, and engraving templates, and file size is a big concern in web graphics for e-commerce sites (as in, google will downgrade you in search results if your pages take too long to load). Inkscape is a far more capable program than just being able to manipulate basic vector shapes. For design work I use jpegs embedded in pdf files because high resolution is more important than compression quality, and email attachment file size is still limited by most mail servers, this is especially the case with things going to/from China. The detail is more important than the quality of the edges at 100% zoom.
For the rare use cases were JPG might actually be advantageous (which - even for gradients - is seldom the case thanks to delta filters
Not true. You can save a 90 quality jpeg from a simple gradient png exported from gimp at a 25% savings in file size with almost no perceivable difference. The less you care about quality, the more you can save, which is why jpeg is useful. It lets you decide on a case-by-case basis. Also, Inkscape's exported gradients are not great to begin with, having banding issues which really need to be solved before it can claim to export high quality raster gradients.
used in PNG compression) it shouldn't be hard to find software designed for working with raster graphics (and offering the respective export formats).
It's not hard to find one, it's a pain to use two programs to fill in a standard and necessary feature for designers. Graphics produced in Inkscape should be able to be exported to the required format.
Regarding how this discussion started: Sometimes it's better to educate users than to give in to wishes that are the result of a lack of knowledge...
I love it when people don't read the arguments presented for using jpegs, and then assume it's lack of knowledge.
For example I'm constantly teaching my students *not* to use JPG compression for scientific plots. I'd love the day where JPG export was cut from all plotting software!
And if Inkscape's mission statement included a scope limited to scientific plots, I'd agree with you completely. :P

Each implementation tries, but it's not GREAT.
A dialog with the slide bar and a small preview. You move the slide and if it's low the preview is ugly, if it goes over a certain amount (using some size guess if exact calculation is too challenging), a "Use PNG instead!" pops out. You both give the functionality and educate on why PNG export from vectorial drawings is better.
Guessing the size of the PNG in advance is most likely next to impossible. And given how long a PNG export takes it's not really feasible to do one every time the export dialog is shown just to gather the file size.
