Meaning apps that don't take advantage of the "latest and greatest" Servlet
API (2.3) specification features, like filters and such.  A lot of "older"
and even newer apps run on Tomcat 3, and a lot of them run on TC4.  People
use both in production environments, and there's no reason why everybody has
to use Tomcat 4 immediately if they do not need the administrative or API
features.  Tomcat 3 has been around for a while and IMHO it's solid.

Purely anecdotal, but I noticed that Tomcat 4 exhibited higher latency at
admittedly light loads on similar hardware in the two cases where I
experimented with migrating an existing, "old" application to Tomcat 4.  I
left them alone (still running!), and used Tomcat 4 for another project
instead.  Could have just been me...could have been a lot of things.
