This is definitely needed, thanks for raising it!
I would like to assign to work on this after finishing some assigned issues of mine.

I think that this one will probably be addressed by #1742, sorry @Xunzhuo, should have linked it earlier.

[Xunzhuo]

That is fine @youngnick, happy to see it is already started, I will help review everything in GWAPI, ping me if you forks need more reviews : )

I linked this over in #1742 as reference material (@arkodg's layout of known timeouts, thanks Arko!) but since we now have a duplicate and #1742 already has a merged PR with a GEP referring to 1742, I'm going to close this one as a duplicate as it seems we can simply continue work there. Let me know if we need to re-open this however, if I've missed something! 🖖
