text: Title: [Question] Deprecation warning for wrapper space attributes?
  Body: ### Question
  
  The latest gymnasium version warns that wrappers reward spec won't be accessible in the same way in v1.0
  I'm not sure how to interpret this:
  ```
  rl/lib/python3.9/site-packages/gymnasium/core.py:311: UserWarning: WARN: env.reward_space to get variables from other wrappers is deprecated and will be removed in v1.0, to get this variable you can do `env.unwrapped.reward_space` for environment variables or `env.get_wrapper_attr('reward_space')` that will search the reminding wrappers.
  ```
  
  My questions are:
  1. Why this deprecation? I saw somewhere that vectorized envs will now be a separated class. I seems from here that wrapped env will distanciate themselves from regular envs. Why are all these classes which were interchangeable become more different? If anything one would expect them to become closer to each other with time.
  2. Specifically for reward spaces: what does this mean in practice? In torchrl, we have a series of wrappers for gymnasium envs, what do we have to do to anticipate these changes?
  3. Is there a way big "customers" of gymnasium would be asked for feedback before deciding these bc-breaking changes in the future? Is there a list of people we can subscribe to that would make us aware of these changes before they are enacted?
  
  Thanks
