Serialization of Spreadsheet objects. Why is it explicitely blocked?

[MarcinOrlowski]

There's a commit a7259de that explicitly prevents serialization of the Spreadsheet object. I have a code that uses legacy version and successfully serializes instances of Spreadsheet for ages, but I'd like to upgrade the package and as serialization is important part of the current flow, I currently stuck.

@MarkBaker as you are the author of that commit, could you please cast some light about the reasons?

I do not know all of the reasons, but we were getting lots of bug reports (see #1757, #1741, and #932), and possibly others; plus a concern that some of the properties were not serializable (resources, SimpleXMLElement, and maybe others).

That said, I believe 1757 is no longer an issue because of the way Dynamic Arrays was implemented, and 1741 can be addressed with any of at least 3 totally trivial changes. I cannot speak to 932; I don't have a good way to test caching. Despite that, It may be time to revisit this decision. I will try to have a PR next week.

Thanks for the follow-up. If that restriction could be lifted, that would be a really great. Fingers crossed :)
