"Why it's a problem not to interfere with my work, and leave it as is?"
It goes against the philosophy of a wiki - collaborative editing. You're wanting exclusive editing. "It's mine. Don't touch it."
"I understand that posting it on the wiki means the ability for anyone to edit the pages, but since there is no other place on this website where I can put them (and have more control over it), I'm forced to use the wiki"
This is a logical fallacy. You're not forced to put them on the wiki at all. You can do the development elsewhere and put them on the website when you're done. But, once they do go into the project wiki, they're freely editable by other community members. You don't get exclusive control over it.
"This isn't completely true. There is at least the web-admin that can do changes that others can't. I doesn't know about others though, but there can be more."
No misdirection please. I think the areas you refer to as specifically the home and download pages. The Documentation area is a wiki and editable by all. Either way, it's not *your* exclusive playground is what I was trying say.
