how are we supposed to have in-buffer linter without flymake when eglot-mode? clippy does not seem to provide that

[yuuyins]

README says

(add-hook 'eglot--managed-mode-hook (lambda () (flymake-mode -1)))

without any explanation, even though flymake-mode works just fine for me and is what eglot is supposed to work with

clippy-mode won't add any of those in-buffer linters

so how?
