I've looked into modifying the Inkscape Spiral tool to make different kinds of spirals and in fact in my current version of SVN have substituted a logarithmic spiral for the Archimedes spiral. However it is non-trivial to include both as the mathematical properties are different (one can start at r=0 while the other never reaches that point).
Yet, as you understand, we cannot accept a patch which would change the rendering of the spirals in existing documents. Perhaps you could include an extension attribute to differentiate between the "old" and "new" spirals.
In my SVN I've also modified the Tiled Clones dialog to allow logarithmic spirals. This could probably be added... it requires adding a^x displacements as well as x^n. See attached PNG.
That would be nice to have.
The modified Function Plotter effect included in SVN can plot different kinds of spirals however it appears to be broken after the changes for "Live Effects".
A lot of filters got broken but they are gradually being fixed one by one. Volunteers welcome :)
