Task-level vars are ignored during 'requires' evaluation

Taskfile.yml

version: '3'

vars:
  FILE_LEVEL: 'file'

tasks:
  echo:
    #requires:
    #  vars: [FILE_LEVEL, TASK_LEVEL]
    vars:
      TASK_LEVEL: 'task'
    cmds:
      - echo '{{.FILE_LEVEL}}, {{.TASK_LEVEL}}'

When running task echo with this file, it succeeds:

$ task echo
task: [echo] echo 'file, task'
file, task

Since both variables are set, uncommenting requires should not change the behavior of task echo. However, it fails with the message: task: Task "echo" cancelled because it is missing required variables: TASK_LEVEL. Task-level variable seems to be ignored during the evaluation of requires.

What is your use case for this?
Since FILE_LEVEL will always be defined, why would you include it in requires?
