I don't see how you can justify such a statement under any circumstances.
Are you seriously suggesting that applications should take additional SECONDS
just to get a connection started?????!????!!!???  Not to mention applications
which may want to have multiple connections open.

2-3 seconds delay sure would be noticed on my machine.  Most of the X tools
I use are up in under a second.

Every time you start an application, it has to open a connection to the X server.
This wants to happen fast; acceptable is only when it is less than human
perception; so this sets an upper bound on a local net of 50 milliseconds or
less.  There are other things that need to be done besides connection setup;
you only get a small fraction of the entire budget of time to play with.
This is easy to do under TCP with current workstations.  Adding several
seconds to connection setup is crazy.
