Is there any chance for my proposed patch to be committed?

Here is a brief comparison about binary and package size increase.
Tested on AR9330, mips, TL MR3220v2

Before applying sha2-hmac patch
root at OpenWrt:~# du -sh $(which dropbear)
161.5K  /usr/sbin/dropbear

After applying sha2-hmac patch
root at OpenWrt:~# du -sh $(which dropbear)
165.5K  /usr/sbin/dropbear

It's about 4K binary size increase.
