Why ports are allowed to be linked with base OpenSSL?

[Yuri]

Uses/ssl.mk allows SSL_DEFAULT=base. I know this has been discussed here 
before, but why is this even allowed? If some ports are built with 
SSL_DEFAULT=base, and some with SSL_DEFAULT=openssl, this will obviously 
cause conflicts when two incompatible openssl libraries will be mapped 
into the same process.


Isn't it better to only allow port OpenSSL for ports, and disallow base 
OpenSSL in ports, so that there will be homogeneity of openssl?
