Having all minor mode descriptions on one page does make sense, because
then you can use isearch.  Imagine you write "xy SPC" and suddenly it
expanded to "foobar".  `C-h m C-s expand' will point you to the
culprit's description (abbrev-mode).

I'd object with the reason above.

Yep, an info link would be nice.  One could enforce that each command's
description contains a link to the relevant info pages, but that would
create a thight coupling between the code and the docs which requires
additional maintenance.

I don't have a opinion on that, but ^L doesn't occur in normal text, so
it makes parsing the *Help* buffer a bit easier.

I don't think that `Ctrl+c Alt+m' is more readable than `C-c M-m'.  And
<mouse-2> may be the right mouse button on your system, but on mine it's
<mouse-3>.  And with some gaming mouse it may be <mouse-17>.
