iam not sure this is such a great alternative

it seems rather inconvenient. why i think so ?
well if it was convenient you would likely have written the working
command and not pointed to the manual

also does this work on all platforms? (windows?)

and ffmpeg supports alot more than files, one could want to do

-reverse 1 -i http://foobar.com/image%d.jpeg

to do that with ln one either needs some remote mounting http thing
(i dont even know how to do that) or download all the images first
which may or may not be practical depending on their number and size

that said, i too prefer if there was a generic+portable+simple
solution using something that works with all comand line tools and
isnt ffmpeg specific
