It's easy to get sick of too much customization. It's another well know
paradox of human pshychology -- we want more choose but too much choice
is bad for you
(http://news.bbc.co.uk/today/hi/today/newsid_8155000/8155505.stm).

There are so many small inconveniences/bugs which I know I can solve
probably in 15-30 minutes by studding the code/docs/customization, but I
continue to leave with those in emacs, sometimes for months and
years. Familiar?

It's a problem in light of yours (2). Everyone wants a consistent
interface.

I agree, levels are not flexible enough (or at least at higher
levels). People tend to agree on the basic fontification like strings,
comments and keywords. But with more fontification levels become a
trouble. For example I can choose to fortify the function call as in
"foo(x, y)" or I can choose to fortify parenthesis. Different people
might choose different things. Also, I might want to fortify {} braces
as they are difficult to distinguish from (), but leave all other paren
syntax untouched.  These things are difficult or impossible to fit into
levels.
