I do not speak for the MW maintainers, but I believe this is to
explicitly prevent the logo from being changable via
[[MediaWiki:Monobook.css]] and [[MediaWiki:Common.css]].  That is,
that changing the logo requires actual back-end access, not simply a
sysop account on the wiki.

What follows is one solution to what you are trying to do - I cannot
help you any more than giving you the exact solution:

1) In an un-altered Monobook.php, locate and remove the style
attribute on the <a> tag under the p-logo div.

2) Add this to the article [[MediaWiki:Monobook.css]]:

 #p-logo a {
   background-image: url(http://server/path/to/regular-logo.gif);
 }

 #p-logo a:hover {
   background-image: url(http://server/path/to/hover-logo.gif);
 }

That's all it takes.  I have tested this in a vanilla MW 1.9.3
install. Good luck!
