Absolutely agreed. Like several others have suggested, I think we
should just go with a "min-width:100px" approach, which is much
clearer.
Though that still doesn't make it clear that it refers to the viewport
size rather than the image size. Or does it?
It also lets us add "max-width", though that may complicate
the resource choosing algorithm a bit.

Does doing so solve any use cases?

Also, since the fallback image participats as a candidate, but you
cannot change its descriptors, you are not free to use any of the images
as the fallback image. You might either want the narrowest image to be
the fallback, or the widest image, or one in between, but the syntax
doesn't allow choice, AFAICT.
To solve this problem, I propose that we allow the src URL to be specified
in srcset, and when it is, don't add src as a candidate. It would be good
with a keyword "inf" or "infinity" as a width descriptor in this case so
you don't need to specify "1x" when you want infinity.
