Agreed. According to my slightly outdated symbols database, the
following ports use it. So it should be easy to check there's no
breakage:

shells/nsh,static
shells/nsh
net/dhcpdump
net/openmdns
net/onioncat
security/ipguard
security/dsniff
security/dsniff,no_x11
net/tcptrace
net/mac-telnet
net/libslirp (probably false positive)
