Perhaps we should return None if value is not a string instance...? Need an opinion here.

I feel like we should convert it to str unless it is None.
I also wonder if we should return None if not value.strip().

Both are easy to implement. I don't particullary mind but I don't feel I am the one to make such decision.

I wonder if we should skip None values in the resulting list.

I was actually thinking of following this PR with another one that would apply some sort of "clear empty items" on all fields returning lists of items.
But later in this comment I was told that by design we should keep processors transparent, so right now I'm not sure how much of post-processing is actually allowed. This particular PR also goes against this philosophy, though I'd argue is relatively non-invasive and seems useful.
I guess decision needs to be made at higher level whenever we want to stick to this design goal or are we deliberately going to break it next release, which would allow this and other similar PR to be included in the library.

+0.5 to these processors.
Even if we are processing str, I feel it is justified to meet the schema requirements, which I feel are for all these fields to be trimmed, even if the schema only says that explicitly for article body.

I think that's fine to strip string fields, but we need to change the documentation. |

Always trim string fields.
For all fields of type
Optional[str]orstrapplystr.strip()through processors.For all fields of type
Optional[List[str]]orList[str]applystr.strip()to all elements through processors.Extract processors to separate classes following approach found in extractors to reduce duplication in code.
