Though I mostly agree with you, your "advice" does have its uses:

in particular see the sections on method combinations.
Thank you; I should've looked it up before incorrectly assuming that you
were talking about "advice" from some Lisps. I initially thought the
original question was getting at something like `defadvice`:

Part of what bugs me is violation of expectations: In Racket, when I
see or use a procedure reference in some code, I expect to get a
particular procedure implementation. (Given a straightforward
understanding of `#lang`, `require`, scoping, and syntax extension.) If
that's instead documented to be a generic, then my expectations change
to the implementation I receive (probably) performing an analogous
operation. (Actually, in Racket, I'd say generics and classes are
usually used only when overriding is definitely happening.)
