Some elements maybe to enlighten you, from someone who is, like you, a 
grateful (?) user of Apache httpd, and not a contributor of code.

As you probably know, Apache httpd is an open source project, and also 
free software.  Basically it means that it is being written by people 
who are not being paid for the time they spend writing it.
Considering that Apache httpd is being used succesfully on literally 
hundreds of thousands of websites worldwide, one would also have to 
admit that these people are competent and know what they are doing.
It also means that you get the result, a piece of software that manages 
hundreds of thousands of websites worlwide and has cost thousands of 
man-hours of work, entirely for free.

Apache httpd is being improved somewhat over time by people who submit 
suggestions, but mainly by people who follow-up these suggestions by 
contributing what is known as a "patch" (a code modification) 
implementing their suggestion.
Such a suggestion, when accompanied by a patch, tends to be taken more 
seriously by the Apache httpd code contributors, than a mere (relatively 
gratuitious) suggestion on a user's mailing list.  It is taken more 
seriously, because it shows that the person who made the suggestion, at 
least looked at the code, understood it to some extent, made some 
change, tested it, and found it to have some benefit and no obvious 
nefarious consequences.
If you are really a programmer, you will understand the world of 
difference between this, and merely making a suggestion on a mailing 
list, based on one particular situation, unverified and uncorroborated 
by anyone else.

The way I personally understand your last paragraph above however, it 
seems to imply that based on the inherent worth of your insight, you 
somehow expect everyone to be in awe, and someone else to do the rest of 
the work for you.
That is not how open source projects work, and certainly not Apache 
httpd, where any apparently harmless change could ruin the day of 10,000 
website administrators.

I am not saying that your suggestion is without merit.  But although I 
am a mere Apache user, knowing how central DNS is to the entire fabric 
and function of the WWW, I would myself expect quite a bit more "backup" 
to such a suggestion, before I even spent some time trying to figure out 
what benefits it could bring, and what other consequences it might have.
Wow, if this option was set in the Apache main configuration, should it 
automatically be inherited by all Virtual Hosts ?  does it mean that SSL 
would not work anymore ? what about "Allow from mycompany.com" ? what if 
some embedded mod_perl or mod_php application tries to do a DNS lookup 
via an Apache library call ?

Does the above provide some insight as to the tongue-in-cheek answers 
you have been getting so far ?
