Types of some attachment metadata has changed

Since r36429 when you use wp_read_image_metadata() the ["image_meta"]["orientation"] is no more an integer but a string.

I've noticed it because it made a BuddyPress unit test fail. I don't know if this could have an impact somewhere, so i thought it was best to report it here just in case.

Looks like it's the case for created_timestamp (int), orientation (int) and aperture (float)? Are there more?

Found this in a list of tickets without a milestone.

I'm not clear what needs to be done here. It seems this was a "let's keep an eye out for adverse effects" ticket, but I don't think any have come up since it has been 6+ years.

I took a look and wp_read_image_metadata() does not seem to have expanded documentation of meta values that may be present, so there are no incorrect types listed. Seems this can be closed out.

I agree with the above comment. Since this has not seen any issues in ~7 years we can close this. Feel free to reopen if incorrect!
