What is the purpose of apache2 having PKGNAME of "apache" (without 2)?

I am working on a tool to install/update packages using the pkg_summary 
database.

My tool can download, but when I chose to download "apache", it fetched:

apache-1.3.37nb2.tgz
apache-2.0.59nb6.tgz
apache-2.2.4nb6.tgz

It seems to me that this should be:

apache-1.3.37nb2.tgz (or apache1-1.3.37nb2.tgz)
apache2-2.0.59nb6.tgz
apache22-2.2.4nb6.tgz (or my preference apache2.2-2.2.4nb6.tgz)

I know this has been discussed before.

Can we please fix this?

This applies to probably other packages too.
