This issue has not been updated in over 15 days. @koko57 eroding to Monthly issue.

P.S. Is everyone reading this sure this is really a near-term priority? Be brave: if you disagree, go ahead and close it out. If someone disagrees, they'll reopen it, and if they don't: one less thing to do!

[koko57]

I'm back and I will start working on this after Stage 3

[koko57]

Still working on it, but tomorrow I should be able to open the PR
