 Yes, `sudo` can be configured to set $PATH for the programs that
it invokes; see sudoers(5) and look for `secure_path`.  If you
don't invoke those from your normal shell, I don't see a problem
removing them from the default.

As for non-sudo PATH, you can always run:
     export PATH=$(getconf PATH)
To get a minimal PATH setting guaranteed to include all POSIX
utilities.
