It's just a matter of Someone(tm) building the new rescue with ftp
or fetch, testing it, and reporting the size change. ;-) With network
setup tools already in /rescue, it sounds as a good idea to consider,
at least.  The needed code pieces aren't giant:

-r-xr-xr-x  1 root  wheel  18956 26 авг 03:31 /usr/bin/fetch
-r--r--r--  1 root  wheel  54750 26 авг 03:27 /usr/lib/libfetch.a

But the crypto bits may need to be disabled:

# ldd /usr/bin/fetch 
/usr/bin/fetch:
        libfetch.so.5 => /usr/lib/libfetch.so.5 (0x28080000)
        libssl.so.5 => /usr/lib/libssl.so.5 (0x2808d000)
        libcrypto.so.5 => /lib/libcrypto.so.5 (0x280ce000)
        libc.so.7 => /lib/libc.so.7 (0x28225000)

Another option is tftp(1). :-)
