As a relative newbie I respectfully disagree (sort of. I guess it depends on what you mean by newbie). There should be plenty of warnings about consequences, and yes there will be more posts (like mine) arising from silly mistakes. But
a. Sometimes there is no choice, even for relative newbies. There was no way I could have got my wireless working in 5.8 without being able to do it. I was originally forced into it in the 2.2 kernel days to get my winmodem working, and back then it took a lot of research to get the gospel truth on how to recompile. There's a lot of misinformation out there in other forums, of bigger distros especially. The TLDP stuff is admirable and thank heavens for the people who can be bothered to do it, but it is usually pretty out of date.
b. Being comfortable with recompiling is really not that hard, and requires surprisingly little other background knowledge if you follow some basic safeguards. I am proof. Sure I'm mucking around with things I don't really understand, but in the end I have always solved the problem and learnt something along the way. My whole experience with linux is mucking around with things I don't understand.
c. IMHO without being able to do it you miss out on two of the greatest strengths of linux, being able to adapt the kernel to your machine, and staying up to date, unlike Windows users (like me) who wait about 5 years each time and then have to pay again for the privilege. And it's a great way to learn about the system.
Admittedly I fiddle with things more than I should. And linux is just a hobby for me, so if I b0rk my linux system it's just another pleasantly futile task to get it working again, in my own time. There are plenty of others like me here I am sure.
I have only learnt to re-compile from kernel tarballs, and don't really understand how to do things from the Vector package, or what extras/Vector-specific things are available, (like, what is bootsplash) so I for one would welcome a Vector kernel howto. I'm not sure what I could do to help but could provide some newbie feedback and support for newer newbies than me.
