Well, since we are in a discussion here a post on the bug list
might be a bit too early. But yes, a enhancement request in
bugzilla will definitely get a response, but on the zooming
behaviour there are enough open bugs right now :)

Well, we have a lot of preferences already and one can have
too much degrees of freedom. When I brought up different sets
of zoom presets available in the preferences, some people were
complaining, that preferences are just a sign of a lack of descision

As you might have seen in the earlier discussion, for some people it is
very important, to get sane ratios like 1:x as magnification factors.
Your approach of course would work, but usually result in ugly
fractions. The list of fractions from the earlier Mails were the result
of a compromise, a move back to "real floats" is not an option.
Personally I believe that only factors based on the n'th roots of two
are reasonable choices, since we usually want to have the double,
quadruple etc. sizes of the images in the list of zoom factors.
For a short time we had something based on the golden mean in CVS,
and it really felt clumsy, because it was so hard to hit the powers of
two as magnification factors...
sqrt(2) gives us two steps between each doubling of the size, and
it seems to be fine enough. I might experiment later with
2**(1/3), but that isn't really urgent now.
