Are you sure?

another broken thing in busybox wget is the -c switch which should enable
resuming of incomplete downloads, but when this option is used with a server
that doesnt support REST it will fail to download at all. iirc this happened
with the zlib.net server.
Proposed fix:

i have not tested the patch yet (mostly because the copied and pasted
diff does not work, and because of Rich's considerations).
what busybox wget should do imo is:
only use "Range" feature when the output file exists, and is smaller
than the total download size.
if both is true, and the server does not support Range, return error
message, otherwise continue download.
