What you are really saying is that it's better to put hacks and crap in 
the tree, and hope someone comes along and does it right, removing the 
hack, while making it even more a living hell for everyone else to 
understand.

So is yours.

That's not why at all.
You haven't seen support because nobody wants to do it right.

See, here is your fatal mistake.
You are making the assumption that users will clean it up, make it work, 
and improve it.
While this may be true in other projects, it's not really true in GDB's 
case.
In fact, it's only true in GCC's case because there are more people who 
understand the intricacies of compilers, and who are qualified to hack 
on the compiler, than their are who understand the intricacies of joe 
random platform's debugger interface.
When it comes to things like drivers and debuggers, users don't really 
help much, unless the architecture is so amazingly easy to understand 
it's absurd. Which it isn't. Having ported sound drivers and whatnot to 
BeOS, and talked with quite a few authors of sound drivers on linux, the 
general consensus is that nobody submits patches. Their is the 
occasional person who really enjoys hacking on undocumented hardware, or 
poorly documented debugger interfaces, and who submits patches, but they 
are very very rare.
So what about the non-platform specific parts of GDB that are 
understandable, and hackable?
well, for the most part, they work great, and people are happy with 
them, and thus don't submit patches.
But just ot prove my point, when is the last time you saw a user submit 
a patch for dwarf2 support, or C++ overload resolution (discounting me), 
or support for a new platform?
It just doesn't happen all that often.

Accepting hackish patches won't change this. It's not going to mean 
random people are going to start submitting more patches. It'll just 
mean one more hack in the tree (Although the patch is starting to shape 
up), and one more hack for the occasional few who want to try to 
comprehend how it works, to sort through.
