Flymake error when third-party package required in init.el

[Y . E .]

Hello,

*Use case*
- Install any package: `M-x package-install <package>`
- Enable flymake: `M-x flymake-mode`
- Add line `(require 'package)` to init.el
- See flymake error: `Cannot open load file: No such file or directory, 
<package>`
- Note that `M-x byte-compile-file` does not produce any errors/warnings.

*Goal*
How to configure flymake or load packages to get rid of this flymake error?

*Additional considerations*
- I'd like to avoid explicitly passing a package's filename to `require`.

- `(setq elisp-flymake-byte-compile-load-path (cons "./" load-path))` fixes the
  issue. But still, it seems weird the current default of this variable doesn't
  work out-of-the-box for the described use case. Am I missing something?
