I agree it would be beneficial to have it all in one and only
one place.

In vanilla Emacs, warnings and suggestions are or can be
outputted from:

- checkdoc.el
- elint.el
- the byte compiler
- the native compiler

In MELPA there are:

- elisp-lint [1]
- package-lint [2]

elisp-lint has the advantage that it is a meta-linter of sort,
as it also outputs warnings from the byte compiler, from
checkdoc, and package-lint.
